The issue was that unless the debug agent was currently under a "suspend all", it would not properly put the virtual thread on the `otherThreads` list, and instead added it to `runningVThreads`. This meant at the end of `insertThread()` the following code tried to do a JVMTI `SetThreadLocalStorage`, which can't be done on a terminated thread.
