That's what I get for replying from an iphone over morning coffee. See also http://semanchuk.com/philip/sysv_ipc/ for Philip Semanchuk semaphore/IPC work as well. Given both multiprocessing and Philip's work are concerned about the shared aspects, I think you're right - FBSD and others support the posix semaphores for non-ipc stuff ok AFAIK (recent benchmark http://www.ioremap.net/node/216). jesse _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
