I'm not sure that this is thread-safe as processors can reorder instructions, so there is no guarantee that memory is written in the expected order. That's one of the problems that C11/C++11 atomics solve. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue1583> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
