I finally figured this threading problem out. Soooo simple. The thread stack size needed to be increased....the default thread stack size on hp-ux is insufficient.
I suggest that change be added to the default Python build process ... or a note added to the README under the HP-UX section at least. Now I see a 'gc' error and crash on program termination. I'll post that error message in a followup post (a new thread for a few topic). Thanks, Blade. -- http://mail.python.org/mailman/listinfo/python-list
