The stack trace attachment shows that there are three threads waiting for
garbage collection to complete, but the thread invoking the garbage collector
is waiting for the threads to report that they are ready.  The question is why
that happened.  Is the garbage collector waiting for a thread that somehow
disappeared, or did the garbage collector fail to receive a notification?
