How do we listen for HANGUP events when using select()? #38

Investigate. If we do, document how it works. If we don't make it so we do and then document that.

The answer is that we don't. There's obviously no way to get hangup events using select() and checking the socket error doesn't really give us a decent way of knowing whether it was a real hangup or not. I'm not sure if there's really any solution to this problem, so people using select() will have to put up with overriding _Channel._handle_error_event() to gracefully hangle lost connections if they find that they're having problems. Testing hasn't revealed any issues with select() so far, though, so that's a good thing.
