Implicit scope handle

[Maurizio Cimadamore]

That is all documented in the javadoc - e.g. acquiring an implicit scope 
is essentially a no-op. The only thing we guarantee is that if you use 
this idiom:

```
var handle = scope.acquire();
try {
    // critical region
} finally {
    scope.release(handle);
}
```

the scope will not be closed inside the critical region (because of the 
reachability fence inside the `release` method).
