Before you get too confident, you might try your code on a multiprocessor machine, under some heavy stress test (or ask one of your collaborators if you don't have access to such a thing). Threaded code that runs on uniprocessors can do very different/unexpected/unwanted things on multiprocessors. -- Paul -- http://mail.python.org/mailman/listinfo/python-list
