non-blocking sys.stdin.read() on win32?

[Laurent Szyster]

There's no way to do non-blocking I/O on STDIN on a Win32.
I don't know why and even never bothered to test it, but I
suppose we can trust Sam Rushing: he did try.

>From Medusa/monitor_client_win32.py:

  # monitor client, win32 version

  # since we can't do select() on stdin/stdout, we simply
  # use threads and blocking sockets.  <sigh>

Sorry to bring bad news,
