Subject: Custom Schedulers: Customize current time and timed waits
Message-ID: <CAPg4LcQMeiR55yeYf9iAeKSERwc2JMvg7dbnQbNYc1iEUgR4yA@mail.gmail.com>

Hello,

I was experimenting with the custom scheduler feature, trying to integrate
it into the open-source library I maintain. For the core part of this
library to work we need to have control/intercept certain parts of the
environment, relevant here are:

1. How threads are scheduled and executed
2. The current time
3. How threads sleep

Since the JVM does not provide a good way to customize these we have to
disallow users from using many normal Java standard library functions and
instead they have to use our custom functions that do allow this. For
example, users have to call `Workflow.sleep` instead of `Thread.sleep`.

Experimenting with the custom schedules it seems like we now could control
how threads are scheduled and executed (amazing!), but we still can't
control the current time or how threads sleep. For example if a thread with
a custom scheduler calls `Thread.sleep` there is no way for the scheduler
to control when that will return, even if the scheduler tries to unpark the
thread the `for` loop in `VirtualThread.sleepNanos` will keep parking it.
In other languages that support a custom scheduler for tasks like Python,
Javascript, Dotnet, Rust or Ruby this sort of behaviour is customizable.

Is there a way currently to customize this behaviour that I have missed or
would this be something the team would be open to exploring in the future?

Thanks,
Quinn

Just to say that this project hasn't decided whether to expose anything 
on schedulers at this time. There is some basic support in the loom repo 
for experimenting and to get more insight into the topic - is that what 
you are experimenting with?

Timed operations, e.g. timed-Object.wait, sleep, ... have to deal with 
spurious wakeup. Are you looking to advance the time and have these 
operations complete early? Or maybe are looking for all time sources to 
be pluggable? Or maybe you are looking for the scheduler to know that a 
virtual thread is doing a timed operation?

Yep! I understand nothing has been decided yet. I just saw
https://github.com/openjdk/loom/blob/fibers/loom-docs/CustomSchedulers.md/
so I built the JVM over the weekend and was experimenting with it since I
think the library I maintain has a interesting use case for schedulers.

For timed operations ideally I would like the virtual thread to request the
scheduler it wants to do a timed operation and the scheduler decides how to
accomplish this. That may be too high level an interface to add since it
looks like more libraries use `java.util.concurrent.locks.LockSupport`. This
is my first time looking at the implementation of some of these low level
calls, but maybe it would be more realistic to allow a pluggable time
source and interception of these parking utilities.

At the moment I?m working on a project that does something similar, although it?s internal and it uses the Espresso continuations API rather than modifying Loom. Porting it to the custom scheduler support in Loom is on the list of things to try. I suspect it won't fit because our alternative threads are different enough that we can?t use java.lang.Thread as a base class. We also have our own wait APIs and leave the JDK?s alone, partly because the semantics and features of our waits are different. Once you get into changing the semantics of built-in operations, which I guess a custom scheduler would very likely do, you?re going to either lose compatibility or lose the ability to add the features you want.

One of the features we use this for is deterministic testing. The main issue you?ll face is the lack of dependency injection in the Java standard library. We build on Micronaut to avoid that problem, and so you can @Inject an InstantSource to get a virtualized clock that can be advanced by test code, and our Thread.sleep replacement respects it. It?s not ideal - obviously if a busy-wait loop occurs inside a library then you have to modify the library to make that hookable. However, you probably have to modify it anyway if the library actually looks at anything expecting the time to have advanced (e.g. if the wait is because of a real delay in an external system). One of the advantages of building at a higher level like Micronaut or Spring is the large consistent library of dependency-injectable things. A lot of the modifications have been done for you already. For instance, you can replace the HTTP client beans and override network timeouts that way. You can also inject j.u.c.Lock implementations.

For deterministic testing you don?t need custom schedulers for virtual threads. If you can control the wait and clock APIs, you can just adjust their parameters. The deterministic testing in our project is more useful because it interacts with the custom wait APIs. It would still be nice if Instant.now() and the lock constructors were using an SPI. But this observations takes you in the direction of wishing that Java had better support for dependency injection. It?s a big part of the most popular Java frameworks. The SPI pattern is expensive enough to implement that many parts of the standard library don?t use it.

Subject: ScopedValue performance declines as number of dynamic bindings
 increases
Message-ID: <BL3PR10MB62334D00326B3A33596F2BB3FE78A@BL3PR10MB6233.namprd10.prod.outlook.com>

Hi,

I've been working on implementing a feature and the ScopedValue preview feature was an excellent fit to a particular design problem I faced.
Reading the source code, I noticed that it seems as though the linked list of value bindings are shared across all ScopedValue instances. This was a bit surprising to me, as this means that the performance of accessing
a ScopedValue binding declines linearly with the number of bindings before it on the stack.

The ScopedValue feature has a long heritage, with historical roots in Lisp and Scheme. The most similar implementation that I know of is that found in Racket, where they are called Parameters[0]. Parameters are also inherited by child threads, and are accessed per thread. Guile, a different Scheme, calls ScopedValue thread-local fluids[1].

Okay, so multiple languages have these things, do they have the same performance implications? The answer seems to be no.
I wrote a number of benchmarks, for Java, Racket and Guile. The Racket benchmark shows no discernible difference in performance, and neither does Guile Scheme, however the Java benchmarks show a very large difference in runtime. It makes sense that the Scheme languages optimize for this case, as they use parameters a lot. For example, with-output-to-file rebinds the current-output-port in order redirect the output to a file. If accessing this variable required traversing a linked list each time, then the performance of the system as a whole would suffer. These languages show how ScopedValues have come to be used by languages which have had these features for a long time. Namely, they provide a reasonable default (current-output-port pointing to stdout), whilst allowing the user to manipulate the parameters in order to change behavior when needed.

I'm wondering about the reasoning and trade-offs here, what do we get with our implementation that the Schemers do not? Maybe we should consider changing our implementation?

Cheers,
Johan

Hi Robert,

Right, I skipped some explanation for brevity. I just ran `time java ScopedTest.java > /dev/null` and `time java ScopedTest2.java > /dev/null` and checked the time difference. That is of course not very granular, but the difference was from 0.6 seconds to 3 seconds, so the noise from VM startup etc doesn't seem very relevant.

You can?t test Java applications that way. I?m sorry but you need to look into using something like JMH. 

Most low level Java designs for infrastructure code like this rely on the JVM being able to optimize away a lot of layers. Your tests don?t allow that to happen.

Can you say a bit more about what you are doing? Mike Hearn mentioned 
deterministic testing but I can't tell from your mails if this is what 
you are doing.

In any case, the experimental interface for the scheduler is 
deliberately minimal. If a virtual thread waits in timed-Object.wait for 
example, then controls returns to scheduler. When the virtual thread can 
continue then its task will be queued to the scheduler to execute. This 
may be triggered by an Object.notify, timeout + monitor?reacquired, 
interrupted + object reacquired. So triggered by the VM or other parts 
of the runtime. Also timeout is just one of the cases that causes a 
thread to continue. It's the same with LockSupport.parkNanos. I don't 
know if you are expecting the custom scheduler (essentially arbitrary 
code) to run at these critical times but right now, the scheduler is 
just used to execute tasks.

Hi Aleksey,

Oooh, that could explain the issue completely. I didn't think about that at all.
The issue basically disappears when compiling first, let me see what happens with a JMH benchmark as well.

As a side note - i would love to learn more about deterministic testing - seems like an oxymoron to me - at least in trying to modify the JVM to simulate determinism directly. I?ve never heard of anything like this working. Clearly, you can write a deterministic simulator (tester) for event flows etc. but afaik these are done in a higher level environment. Even real time Java was never deterministic so I don?t see how this would be useful - but I?m curious.

I predict JMH would show the same thing.

javac is not very fast when cold; this is also why we use it as go-to example in AOT cache studies. 
I would also expect compiling deeply nested lambdas (like in ScopedTest.java) makes the javac code 
fairly recursive, which again plays interestingly with JIT compilation. It is still 
actionable/interesting to figure out what can be improved there. Looks fairly weird we spend >3 
seconds compiling a seemingly "easy" source. Submit a tools/javac RFE, let compiler folks have fun 
with it?

The reason in the difference in the compile times is related to the number of error messages generated.

If you compile using ?enable-preview you will see that the compile times are nearly identical.

Hi Aleksey,

I re-wrote my benchmarks to use JMH and I used Blackhole::consume instead of the S.o.println. The entire point of the println was to signal to the compiler 'this has to happen'. I kept the 100k iterations, as I didn't want the setup of the 100 dynamic bindings to dominate (or perhaps they are? Not sure).

I ended up with the following results:


(This is the test of just doing MISSING.orElse)
Result "org.openjdk.bench.java.lang.ScopedValues.ScopedValuesAreFasT":
  815142.530 ?(99.9%) 17764.324 ns/op [Average]
  (min, avg, max) = (790345.594, 815142.530, 835566.013), stdev = 11750.000
  CI (99.9%): [797378.206, 832906.854] (assumes normal distribution)

(This is the test with MISSING.orElse within the 100 dynamic bindings)
Result "org.openjdk.bench.java.lang.ScopedValues.ScopedValuesAreSlow":
  18847997.203 ?(99.9%) 587930.099 ns/op [Average]
  (min, avg, max) = (18176298.357, 18847997.203, 19523500.462), stdev = 388879.358
  CI (99.9%): [18260067.104, 19435927.301] (assumes normal distribution)


That's 815142 ns/op vs 18847997ns/op, a pretty large diff still ('contested' case takes 23x longer).

Am I messing up my benchmarks once again, but in some different way?

Here's the branch and source: https://github.com/openjdk/jdk/compare/master...jdksjolen:jdk:scopedvaluejmhs

I just put the benchmark into the pre-existing ScopedValues.java, should just be a copy and paste and be done if you've got a JDK build set up.
The tests are run on linux-aarch64.

I predict JMH would show the same thing.

javac is not very fast when cold; this is also why we use it as go-to example in AOT cache studies.
I would also expect compiling deeply nested lambdas (like in ScopedTest.java) makes the javac code
fairly recursive, which again plays interestingly with JIT compilation. It is still
actionable/interesting to figure out what can be improved there. Looks fairly weird we spend >3

Correction, that is not the case - I see a 3x compile time difference.

This doesn?t look correct:

        for (int i = 0; i < 100_000; i++) {
            bh.consume(MISSING.orElse("hello world"));
        }

why are you looping 100k times there?

One last benchmark for today: I added a benchmark that binds the MISSING ScopedValue at the end, so it's like the slow benchmark but we don't need to traverse anything to find the binding.
That turns out to be even faster:

Subject: Re: ScopedValue performance declines as number of dynamic bindings increases

Hi Aleksey,

I re-wrote my benchmarks to use JMH and I used Blackhole::consume instead of the S.o.println. The entire point of the println was to signal to the compiler 'this has to happen'. I kept the 100k iterations, as I didn't want the setup of the 100 dynamic bindings to dominate (or perhaps they are? Not sure).

I ended up with the following results:


(This is the test of just doing MISSING.orElse)
Result "org.openjdk.bench.java.lang.ScopedValues.ScopedValuesAreFasT":
  815142.530 ?(99.9%) 17764.324 ns/op [Average]
  (min, avg, max) = (790345.594, 815142.530, 835566.013), stdev = 11750.000
  CI (99.9%): [797378.206, 832906.854] (assumes normal distribution)

(This is the test with MISSING.orElse within the 100 dynamic bindings)
Result "org.openjdk.bench.java.lang.ScopedValues.ScopedValuesAreSlow":
  18847997.203 ?(99.9%) 587930.099 ns/op [Average]
  (min, avg, max) = (18176298.357, 18847997.203, 19523500.462), stdev = 388879.358
  CI (99.9%): [18260067.104, 19435927.301] (assumes normal distribution)


That's 815142 ns/op vs 18847997ns/op, a pretty large diff still ('contested' case takes 23x longer).

Am I messing up my benchmarks once again, but in some different way?

Here's the branch and source: https://github.com/openjdk/jdk/compare/master...jdksjolen:jdk:scopedvaluejmhs

I just put the benchmark into the pre-existing ScopedValues.java, should just be a copy and paste and be done if you've got a JDK build set up.
The tests are run on linux-aarch64.

Sure, to be clear I am not doing deterministic testing. I maintain a
durable execution framework in Java (https://github.com/temporalio/sdk-java).
To give a very brief overview, users can write "programs" (we call them
workflows) using our APIs and we'll make them fault tolerant. We do this by
recording what the program is doing into an event log so the workflow can
be resumed if the original host crashes. To be able to replay the event log
and resume the program we need the workflow to be deterministic.
Obviously that requirement is problematic when multiple threads are
involved so we have to disallow users from using the standard java library
to start threads and use our wrappers instead. that we can make
determentisic.

In most of the other languages we support like Python, Ruby, Dotnet, Rust,
Javascript we can control the thread/task scheduling so users can use more
of the languages native constructs. This makes our Java SDK harder to use
than some of our other SDKs.

Yeah I understand that the current experimental interface is deliberately
minimal right now. I just wanted to give my feedback/suggestion as a user
who has, in my humble opinion, an interesting use case that a lot of other
languages with a custom scheduler do support.

Yep I am aware of that. Each "workflows" thread's execute in a serialized
fashion. Workflows themselves are like processes and are not allowed
to communicate with each other except over specific determentics channels.
I do the same in my custom scheduler.

The problem with removing the loop is that you'll end up measuring the cost of setting up the dynamic bindings, and not really the cost of traversing them. I'm not sure how you can set up the dynamic bindings as setup and have the benchmarked code run within that dynamic context. It's unfortunate, but the blackhole should prevent (and seems to do so) most optimizations of the loop.

Subject: Re: ScopedValue performance declines as number of dynamic bindings increases

Hi Aleksey,

I re-wrote my benchmarks to use JMH and I used Blackhole::consume instead of the S.o.println. The entire point of the println was to signal to the compiler 'this has to happen'. I kept the 100k iterations, as I didn't want the setup of the 100 dynamic bindings to dominate (or perhaps they are? Not sure).

I ended up with the following results:


(This is the test of just doing MISSING.orElse)
Result "org.openjdk.bench.java.lang.ScopedValues.ScopedValuesAreFasT":
 815142.530 ?(99.9%) 17764.324 ns/op [Average]
 (min, avg, max) = (790345.594, 815142.530, 835566.013), stdev = 11750.000
 CI (99.9%): [797378.206, 832906.854] (assumes normal distribution)

(This is the test with MISSING.orElse within the 100 dynamic bindings)
Result "org.openjdk.bench.java.lang.ScopedValues.ScopedValuesAreSlow":
 18847997.203 ?(99.9%) 587930.099 ns/op [Average]
 (min, avg, max) = (18176298.357, 18847997.203, 19523500.462), stdev = 388879.358
 CI (99.9%): [18260067.104, 19435927.301] (assumes normal distribution)


That's 815142 ns/op vs 18847997ns/op, a pretty large diff still ('contested' case takes 23x longer).

Am I messing up my benchmarks once again, but in some different way?

Here's the branch and source: https://github.com/openjdk/jdk/compare/master...jdksjolen:jdk:scopedvaluejmhs<https://urldefense.com/v3/__https://github.com/openjdk/jdk/compare/master...jdksjolen:jdk:scopedvaluejmhs__;!!ACWV5N9M2RV99hQ!Kf4V8MGGzPh3EaRPIZemTDbQl3VmKGTB7_FHY31MQsK2eZqGoNR_Xcv-a_r8ABZQpqHXt1JlbIgQYAgzvMk$>

I just put the benchmark into the pre-existing ScopedValues.java, should just be a copy and paste and be done if you've got a JDK build set up.
The tests are run on linux-aarch64.

The issue basically disappears when compiling first, let me see what happens with a JMH benchmark as well.

I predict JMH would show the same thing.

javac is not very fast when cold; this is also why we use it as go-to example in AOT cache studies.
I would also expect compiling deeply nested lambdas (like in ScopedTest.java) makes the javac code
fairly recursive, which again plays interestingly with JIT compilation. It is still
actionable/interesting to figure out what can be improved there. Looks fairly weird we spend >3
seconds compiling a seemingly "easy" source. Submit a tools/javac RFE, let compiler folks have fun

You can do that using the JMH apis - it?s pretty easy.

?Deterministic testing? might be a misleading term. I mean driving a single threaded construct through tests involving situations like timed waits, synchronization with other threads, IO errors and so on, but in a more natural way than you could achieve with normal Java constructs. For instance: if a program wants to wait for five minutes, the test doesn?t have to wait. If  a thread sleeps waiting for some signal to be fired then you can know immediately once it reaches that point in the program, fire the signal and then resume it.

Normally when testing code like that you face the problem of your test harness needing to synchronize with the code under test to ensure events happen at the right times, which in turn can mean a lot of test-related concerns intruding upon production code. Our framework lets you single step a thread in a blocking manner up to the next wait and advance a virtualized clock which the waits respect. If you are deterministically testing two threads at once, you can single step one thread, do something, single step another, and so on. So they advance ?deterministically? in the test and you can white-box assert on their state at each suspension point.  Of course, they still have to synchronize with each other in some way to be correct in production.

Does that explanation make sense?

Can you say a bit more about what you are doing? Mike Hearn mentioned deterministic testing but I can't tell from your mails if this is what you are doing.

In any case, the experimental interface for the scheduler is deliberately minimal. If a virtual thread waits in timed-Object.wait for example, then controls returns to scheduler. When the virtual thread can continue then its task will be queued to the scheduler to execute. This may be triggered by an Object.notify, timeout + monitor reacquired, interrupted + object reacquired. So triggered by the VM or other parts of the runtime. Also timeout is just one of the cases that causes a thread to continue. It's the same with LockSupport.parkNanos. I don't know if you are expecting the custom scheduler (essentially arbitrary code) to run at these critical times but right now, the scheduler is just used to execute tasks.

Only the first time you use it: thereafter, the value is cached, and if 
you use it repeatedly in a method, hoisted into a register.

However, we don't cache failure. One reason for this is that the scoped 
value cache is created lazily, and we don't want to create it if all a 
thread is doing is using a scoped value to detect recursion. Also, we 
don't want to kick a value out of the cache for the sake of a failure. 
We can review this decision if the negative case turns out to be worth 
caching.

Finally, we don't expect to see huge numbers of scoped values in use. I 
guess there may be some edge cases where it might be appropriate, but I 
don't think this will be a common pattern.

We want to be able to share a set of scoped values between parent and 
child threads with (near-)zero time and space overhead, so whatever 
structure contains them should be immutable. We want to be able to bind 
(and unbind) a scoped value in constant (hopefully very low) time, so 
rebinding can't, say, update a hash map. We want repeated lookups to be 
very fast.

We expect scoped values to be created as static finals, and much 
optimization depends on that. We expect to see small numbers of scoped 
values active at any time.

Finally, if you're aware of any application need for large numbers of 
scoped values, I'm interested to hear about it.

Have a look at 
https://github.com/openjdk/jdk/blob/master/test/micro/org/openjdk/bench/java/lang/ScopedValues*.java, 
which does exactly that.

Sounds good to me. I'd expect the most ergonomic way of providing a default value is to fail the lookup and use orElse to supply the default. Otherwise, supplying a default value would require you
to install it at the entry point of the program, before any thread creation or stacks have grown, and even that is a simplified view of the issue at hand. My bet is on the negative case being important to cache,
but we don't have to bet so let's await data instead.

Right, so was using ThreadLocal discarded as an idea because of the usage of a hashtable?

Otherwise, ScopedValue could be modelled as

class ScopedValue<V> {
  record SV(V value, SV next) {};
  ThreadLocal<SV> stack;
}

Of course, this is also discarding any caching. I guess the copying of ScopedValue bindings taking as little time as possible is important, because of virtual threads.

I'm not sure how it has been imagined that ScopedValues will be used. If ScopedValue becomes a popular feature, then what's interesting is what happens when you start using many libraries in your program.
Each library may have a few instances of ScopedValues, but an execution thread will have the same amount of ScopedValues as all of the libraries are using (in the worst case).
This leads to a peculiar situation where the performance of your program may degrade in an unexpected manner. Perhaps I only have a lively imagination.

I do not. Fans of functional programming will however recognise that ScopedValue (dynamic binding for installation of handlers) and Continuation (one-shot delimited continuation to provide to the handler) forms the semantic basis for an algebraic effect system.
If the Continuation API is exposed publically (or coroutines for Java are implemented) in the future, then we'll probably see some heavy use of ScopedValues in some libraries and codebases. That might be a niche area of use, however.
Here's a paper on exactly what I'm talking about: https://www.logic.cs.tsukuba.ac.jp/~sat/pdf/tfp2020.pdf 

All the best,
Johan Sj?l?n

PS.
Thanks for the ScopedValueExecutorService example link

It makes complete sense now, but I wouldn?t do it that way? :) with some caveats? If you have a truly time dependent system - like ?this event can ONLY and MUST happen once per day?, I would argue you have a fairly brittle system, and instead, be somewhat idempotent and if the event occurs multiple times in a day subsequent ones are ignored, or more simply redefine the concept of ?day? into a relative timespan. Similarly, for something like a ?daily rollover?, the process I would use is a ?rollover time or last rollover? instead so you can make the interval whatever it needs to be for efficient testing (a few milliseconds, and order the prior transactions).

I just find that systems that are absolute time based rather than relative end up being very brittle.

Obviously many safety systems have minimum absolute response times but everything should be relative to the event time.

I think what you are doing is very interesting though.

Subject: ScopedValue structured forking/forwarding API
Message-ID: <CAN8t40fzVkyy7NbH_=EqNvkz2Q40s4qocV6WoO8HqM=XwSpjJw@mail.gmail.com>

TLDR: The email reasons on the topic of ScopedValue structured forking
API, which is a way to forward ScopedValues to child tasks, even if
users use structured concurrency API different from
StructuredTaskScope

Lately, I've been experimenting with ScopedValue API to see how we
could integrate with it in kotlinx.coroutines library
https://github.com/Kotlin/kotlinx.coroutines

Currently, ScopedValue and StructuredTaskScope work nicely together.
Since both are structured, ScopedValues are forwarded to all
StructuredTaskScope children tasks.

    public class ScopedValue_and_StructuredTaskScope {
        public static ScopedValue<String> userName =
                ScopedValue.newInstance();

        public static void main() throws InterruptedException {
            ScopedValue.where(userName, "Duke").call(() -> {
                try (var scope = StructuredTaskScope.open()) {
                    scope.fork(() ->
                            // Prints "Duke"
                            System.out.println(userName.get()));
                    scope.join();
                }
                return null;
            });
        }
    }

And as we know, ScopedValues are not forwarded to manually created
threads/thread-pools since they are generally
unconstrained/unstructured.

    public class ScopedValue_and_Executors {
        public static ScopedValue<String> userName =
                ScopedValue.newInstance();

        public static void main() throws Exception {
            ScopedValue.where(userName, "Duke").call(() -> {
                try (var pool = Executors.newFixedThreadPool(1)) {
                    pool.submit(() -> {
                                // Throws
                                //
                                // java.util.NoSuchElementException:
                                //     ScopedValue not bound
                                System.out.println(userName.get());
                            })
                            .get();
                }
                return null;
            });
        }
    }

>From what I read in the source code, ScopedValues and
StructuredTaskScope are integrated via internal APIs ? all scoped
values are captured by
jdk.internal.vm.ScopedValueContainer.captureBindings() API which is
called inside the jdk.internal.misc.ThreadFlock constructor.

Unfortunately, external libraries can't use this API, and it's clear
why, I am not asking to open these APIs up, as it would actively work
against the ScopedValues goals.

But I have come with an idea of the following "structured snapshot"
API which is symmetrical to StructuredTaskScope API:

    public class Main {
        public static ScopedValue<String> userName =
                ScopedValue.newInstance();

        public static void main(String[] args) {
            ScopedValue.where(userName, "Duke").call(() -> {
                try (ScopedValue.Snapshot bindings =
                         ScopedValue.snapshot()) {
                    try (var pool = Executors.newFixedThreadPool(1)) {
                        pool.submit(() -> {
                            bindings.forward(() -> {
                                // Should prints "Duke"
                                System.out.println(userName.get());
                            });
                            // Throws
                            //
                            // java.util.NoSuchElementException:
                            //     ScopedValue not bound
                            System.out.println(userName.get());
                        }).get();
                    }
                    bindings.join();
                }
                return null;
            });
        }
    }

ScopedValue.Snapshot is an AutoCloseable object that internally
captures all the bindings from the current Thread. Next, users can
forward all the captured values to child threads by calling
ScopedValue.Snapshot.forward inside the child thread. (All names are
WIP)

ScopedValue.Snapshot would have to maintain the integrity and make
sure that the values are indeed forwarded structurally. Basically,
most of the constraints can be taken from StructuredTaskScope:

- Once ScopedValue.Snapshot.close is called, all subsequent calls to
  ScopedValue.Snapshot.forward would throw an Exception.
- If there are still ongoing ScopedValue.Snapshot.forward calls that
  didn't finish yet, ScopedValue.Snapshot.close would block to wait
  for all of them and then throw an exception requiring an explicit
  ScopedValue.Snapshot.join call (Similar to how
  StructuredTaskScope.close works)
- ScopedValue.Snapshot.join would block and wait for all
  ScopedValue.Snapshot.forward calls to finish
- ScopedValue.Snapshot.join can be called only on the same thread
  where the respective ScopedValue.snapshot was called.

But we have to add 2 more constraints which are unique to
ScopedValue.Snapshot API:

- ScopedValue.Snapshot.forward should check that there are currently
  zero scoped value bindings in the current thread.
- ScopedValue.Snapshot.forward cannot be called on the same thread
  where the snapshot was taken.

The motivation for the first restriction is to make sure that
ScopedValue.Snapshot API couldn't be used to unpredictable override
*all* the current scoped value bindings.

The second restriction is to just forbid ScopedValue.Snapshot.forward
calls that don't make sense.

The 2 restrictions that I'm describing are emerged after reading this
previous thread on the topic of Snapshots
https://mail.openjdk.org/pipermail/loom-dev/2023-May/005664.html
https://mail.openjdk.org/pipermail/loom-dev/2023-June/005699.html

The thread is quite lengthy, but I think the conversation boils down
to the following messages:
- https://mail.openjdk.org/pipermail/loom-dev/2023-June/005722.html
- https://mail.openjdk.org/pipermail/loom-dev/2023-June/005732.html
- https://mail.openjdk.org/pipermail/loom-dev/2023-June/005728.html

which basically says that unpredicatably overriding *all* scoped
value bindings is an anti-pattern.

## Use cases

*Use case 1.* The API would be useful for any third-party libraries
that implement structured concurrency. kotlinx.coroutines is an
example of such a library.

If you are wondering why can't kotlinx.coroutines just use
StructuredTaskScope under the hood. The answer is: because
kotlinx.coroutines allows configuring which threads to use to
schedule coroutines on. It's a common scenario for users to schedule
their coroutines on the main UI thread for example.

*Use case 2.* StructuredTaskScope itself can use this public API to
integrate with ScopedValues.

## Discussion

Unfortunately, the email ended up being bigger than I wanted it to be,
but hopefully it makes sense.

I would love to hear your thoughts on the idea. I am sure that you
have already discussed it in some form internally, but hopefully this
email brings more use cases.

I realize that ScopedValues are scheduled for release in Java 25,
thankfully, the idea here is something that can be released
independently in later versions as an addendum. (shall you decide that
the idea is even a valid use case)
