I pity anyone who has to debug problems caused by monkeypatching the socket module... I wish people would stop trying to solve problems with monkeypatching in python. There are better solutions. Cool idea other than that, though.

Does anyone know of any large-scale projects using this library? It would be interesting to see how it performs in the real world - not needing to use OS threads means that maybe you won't have as much trouble with the GIL, but on the other hand, operations like socket.read() are supposed to release the GIL while they block anyway.
