Antoine Pitrou added the comment: I think a lock is still needed for cache misses. The dict operations (set and del) can release the GIL (as well as course as the PyObject_Call()), therefore you might end up with duplicate list links for a given key.
(and given cache misses are supposed to be much more expensive anyway, I don't think acquiring a lock there is detrimental) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14373> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
