Virtually all I/O calls in pure Python are blocking calls.  Did you mean
to ask about non-blocking I/O?

Well, any time I hear "high performance," I start to wonder whether
Python is really the right choice.  How much performance do you need? 
WSAAsyncSelect is a pretty snazzy way to deal with a socket server, and
