Hmmm, if connecting to 'localhost' isn't immediate, what is? Because
that's how I tested it. (Not that I'd rely on connect() *not*
connecting immediately, but on my Windows box it obviously doesn't.)

/me looks in Python docs and gasps in suprise
Oh my, how could I have overlooked that? That's pretty useful, thanks.
/me studies timeoutsocket.py
Oh, dear, connect_ex() is nowhere to be found in there. Tim O'Malley
