Tim Peters added the comment: Without _stopped, join() can simply wait to acquire _tstate_lock (with or without a timeout, and skipping this if _tstate_lock is already None). Etc ;-) Of course details matter, but it's easy. I did it once, but the tests joining the main thread failed and I put the code on hold. I'll dust it off when the buildbots are all happy with the current changes.

We'd have to ask Guido ;-) Best guess is that Condition supplied all the machinery to make Event.wait() work correctly, including waking all waiters up when the Event gets set. > isn't an Event actually simpler than a Condition?) Events are indeed simple :-) There are many ways to implement them, but "ain't broke, don't fix" seems the right approach to me here. In effect, if we get rid of _stopped, the code remaining will be much like an Event implementation built on the plain _tstate_lock lock. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18808> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
