Chris, Thread.join() is implemented using a lock, and the acquisition of a lock is uninterruptible. (See http://docs.python.org/lib/module-thread.html) Therefore, your main thread will block until the other thread terminates or the process is forcibly killed. Even if it could be interrupted, I don't think there's any way to raise that exception in the other thread. (Python's threading support leaves something to be desired when compared to, say, Java.) -- David -- http://mail.python.org/mailman/listinfo/python-list
