Presumably you could have simplified things by just waiting for all
threads to stop (instead of just waiting for non-JNI threads) before
GC'ing, but then you might have to wait an arbitrarily long time,
because a JNI thread could be doing something slow, sleeping, etc.

In other words, this is the only reason I can think of for doing it
the way you do (and indeed a good one)... but are there any others
I'm missing?

Thanks,
