Note that win32 Python's socket module doesn't have a MSG_DONTWAIT
constant defined. So the following code will fail on windows machines.

+                self.__connection.sock.recv(1,
+                                            socket.MSG_PEEK | 
+                                            socket.MSG_DONTWAIT)

Good job with this patch. It would've been interesting to have a flag to
switch to old http1.0 and see the differences in terms of performance.
