[issue9205] Parent process hanging in multiprocessing if children terminate unexpectedly

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Here is an updated patch. Much of it consists of changes in the Windows Connection implementation, where I had to use overlapped I/O in order to use WaitForMultipleObjects on named pipes.

test_concurrent_futures sometimes blocks (under Windows), I'll try to debug.
