I know that in some cases in the past I've had to bypass a Queue's use of threading objects for waiting for a queue to unblock because of the increased overhead (and latency as the timer increases) of the busy loop. On windows, replacing it with an implementation using WaitForObject calls with the same timeouts I would have used with the Queue performed much better, not unexpectedly, but was non-portable. The current interface to the lowest level locks in Python are certainly generic enough to cross lots of platforms, but it would definitely be useful if they could implement timeouts without busy loops on those platforms where they were supported. -- David -- http://mail.python.org/mailman/listinfo/python-list
