I've also ran the jython 2.1 installer on kaffe
configured to use the interpreter engine. In this
case, the first crash doesn't occur, independently
whether the limit is 10 or 50. I've attached the
actual exception stack traces in the gdb.

This seems to indicate that jit3 is playing some games
with jthreads and forgetting to call
jthread_enable_stop. Could you take a look at it?
