Since proxies for locks/semaphores are supposed to work the same way as the proxied object from threading, one could argue that the lack of support in 3.2 was a bug.

Ok; if it's a bug it should have a NEWS entry, though.

I notice now that multiprocessing..acquire() and threading..wait() treat negative timeouts as zero timeouts. On the other hand, threading.*.acquire() treat negative timeouts as infinite.

Maybe these inconsistencies should be documented or eliminated?

I don't know. Ideally both would have raised ValueError on negative timeouts, but it's probably too late :-)

cheers

Antoine.
