The kernel should remove the mapping when your process exits anyway -- otherwise the world would be left in an inconsistent state if your process got killed by SIGKILL for example. > Do Python extensions have d'tors? No. But you can cheat: stash some object whose tp_del slot does your cleanup in your extension's module under some funny name. (And woe betide anyone who dels the funny name prematurely!) I'm not sure I'd bother. -- [mdw] -- http://mail.python.org/mailman/listinfo/python-list
