Raymond, please stop hijacking issues. This doesn't have anything to do with multiprocessing and there are already four core developers in the nosy list. If you really want to assign it to someone else, please at least wait for a month or ask if they have time to commit the patch first. Unless I'm missing something, this doesn't look like a release blocker to me and definitely doesn't look like some 6 years old ancient issue (the first message was posted three weeks ago) so there is no urgency here.
