I'm afraid I don't know my way around parrot, er, at all - but I'm
willing to learn.
Ah, Mac OS 10.5 has dtrace - which I hadn't tried before but turns out
to be rather cool. Anyway, attaching to parrot once it's hung suggests
that it's deadlocked (I'd pretty much inferred that from the fact that
it's CPU load goes to zero and I'm sure you knew that anyway).
I have six threads - all waiting in __semwait_signal apart from one
whose call stack looks like
thread_start -> _pthread_start -> select$DARWIN_EXTSN
If that kind of information helps at all I can try to work out a
little more of what dtrace is actually doing.
