You are already hosed if you have two threads calling into Python, because you didn't properly acquire the GIL. I can't help beyond that; try using the mailing list http://mail.python.org/mailman/listinfo/capi-sig -- Aahz (a...@pythoncraft.com) <*> http://www.pythoncraft.com/ Weinberg's Second Law: If builders built buildings the way programmers wrote programs, then the first woodpecker that came along would destroy civilization. -- http://mail.python.org/mailman/listinfo/python-list
