"Atomic" was maybe the wrong word. For implementations with a GIL the GIL ensures there are no visibility issues. According to Antoine's link, Jython uses ConcurrentHashMap for its dicts, and IronPython uses a locked map. So in those cases also there are no visibility issues. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17389> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
