Nathaniel Smith added the comment: Sure, but whatever overhead it has, it has. Once we're paying for it, new keys are free (at yield/resume time).
Compared to a bare thread-local it probably has somewhat higher overhead when we have to check it, but (a) that's why PEP 550 has a clever caching mechanism, and (b) you don't have to check it until you have a pending signal, and you almost never have a pending signal. Anyway, we can wait until PEP 550 settles down before making any commitment here... ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31388> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
