There are two internal threads running, one handling events, the second
does select and catches signals. That might be the problem with PTH.

Please try this:
$ parrot hangs.pasm
[ second console ]
$ ps axw | grep [p]arrot
$ gdb parrot <the_pid>
gdb> thread 1
gdb> bac
gdb> thread 2

Yes that's true. But the event thread wakes up the io_thread (s.
stop_io_thread). This seems to fail with PTH as it doesn't preempt.
Looking at the code, this seems to happen, when a thread is created and
never started. The main interpreter tries to join that thread
nethertheless. I've set another flag which should cure this flaw.
