It was done to support making timeout sockets work properly. As they
existed previously, timeout sockets wouldn't work with protocols which would
most likely use them: higher level modules such as httplib, which call
sock.makefile(), then call readlines?() on the resulting file object.

I think it would be easier for the minority of programs that care about the
20% performance loss to simply set
import socket, _socket
socket.socket = socket.SocketType = _socket.socket
I don't know about you, but fast and incorrect don't help me much.
Feel free to submit a patch which improves performance but maintains proper
behavior in the face of timeouts (that is, allows test_urllibnet to still
