Subject: For some reason sys.stdin may be None on Windows, and makes test_multiprocessing... 
X-Git-Tag: v3.0b3~9

For some reason sys.stdin may be None on Windows, and makes test_multiprocessing fail.
Since we are closing the fileno anyway, the best is to skip this part.

Now test_multiprocessing should pass on Windows.
