Using gevent with python xmlrpclib

Question

Hello! Is it possible to use python's standard libs xmlrpclib with gevent? Currently i'm tried to use monkey.patch_all(), but without success.

from gevent import monkey
monkey.patch_all()

import gevent

import time

import xmlrpclib
from SimpleXMLRPCServer import SimpleXMLRPCServer

import urllib2

def fetch(url):
        g = gevent.spawn(urllib2.urlopen, url)
        return g.get().read()
def is_even(n):
    return n%2 == 0

def req(url):
        return fetch(url)

server = SimpleXMLRPCServer(("localhost", 8000))
print "Listening on port 8000..."
server.register_function(is_even, "is_even")
server.register_function(req, "req")
server.serve_forever()

urllib2.urlopen is blocking server. It looks to me, that monkey.patch_all did not patched socket, that's why it blocks.
