I don't know how you define simple. In order to be able to have separate GILs you have to remove *all* sharing of objects between interpreters. And all other data structures, too. It would probably kill performance too, because currently obmalloc relies on the GIL. So I don't see much point in continuing this thread. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ 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
