[issue19612] test_subprocess: sporadic failure of test_communicate_epipe() on Windows 8

[STINNER Victor]

STINNER Victor added the comment:

If I add a sleep of 1 second before stdin.write(), the test always fail with OSError(22, "Invalid parameter"). So it becomes obvious that the write fails if the process already exited.

Attached patch should fix the issue. Can someone review it?

The test fails also on Python 3.3.
