(For some reason the OP hasn't come through to groups.google.com.. odd) Note that it won't interrupt any blocked I/O, which is often what you need the most. If your threads are CPU-bound you can simply have them check a flag and exit if it becomes True. -- http://mail.python.org/mailman/listinfo/python-list
