Summary: memory leak in socket.getaddrinfo

Initial Comment:
Function getaddrinfo of the socket module
fails to free system allocated result when the call is
successful
(but it does on error). Il should call freeaddrinfo to
free res0
before returning Python result.

This leak is also affecting httplib and urllib because
since Python 2.2, httplib.HTTPConnection.connect method
does call socket.getaddrinfo.

Small test program showing off the leak:

import socket, time

while 1:
    res = socket.getaddrinfo('localhost', 80, 0,
socket.SOCK_STREAM)
    time.sleep(0.01)


Tested with Python 2.2.1 under Linux 2.4
