I have a multi-threaded CPython program, which has up to four threads. One thread is simply a wait loop monitoring the other three and waiting for them to finish, so it can give them more work to do. When the work threads, which read web pages and then parse them, are compute-bound, I've had the monitoring thread starved of CPU time for as long as 120 seconds. It's sleeping for 0.5 seconds, then checking on the other threads and for new work do to, so the work thread isn't using much compute time.
How exactly are these waiting and checking performed? Kiuhnm -- http://mail.python.org/mailman/listinfo/python-list
