[New-bugs-announce] [issue11668] _multiprocessing.Connection.poll with timeout uses polling under Windows

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

This impacts higher-level APIs such as Queue.get() with a positive timeout.
I'm not sure whether it's easily possible to fix this. A Google search seems to suggest that the pipe could be opened with "SYNCHRONIZE" access rights (?) and then WaitForSingleObject() be used on the handle.
