Secondly, I think that by thinking this through, we can come up with a suitable event loop framework for Python (probably similar to what Skip is proposing) that works without having to resort to threads. So we give users a choice: use the event loop if possible or preferable, and use a thread otherwise. --Michiel.. -- Michiel de Hoon Center for Computational Biology and Bioinformatics Columbia University 1150 St Nicholas Avenue New York, NY 10032 _______________________________________________ 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
