Summary: poor performance in xmlrpc response

Initial Comment:
xmlrpclib.Transport.parse_response() (called from 
xmlrpclib.Transport.request()) is exhibiting poor 
performance - approx. 10x slower than expected.

I investigated based on using a simple app that sent a 
msg to a server, where all the server did was return 
the message back to the caller.  From profiling, it 
became clear that the return trip was taken 10x the 
time consumed by the client->server trip, and that the 
time was spent getting things across the wire.

parse_response() reads from a file object created via 
socket.makefile(), and as a result exhibits 
performance that is about an order of magnitude worse 
than what it would be if socket.recv() were used on 
the socket.  The patch provided uses socket.recv() 
when possible, to improve performance.

The patch provided is against revision 1.15.  Its use 
provides performance for the return trip that is more 
or less equivalent to that of the forward trip.
