python urllib2 timing

I'd like to collect statistics related to how long each phase of a web request takes. httplib offers:

def run(self):
    conn = httplib.HTTPConnection('www.example.com')
    start = time.time()
    conn.request('GET', '/')
    request_time = time.time()
    resp = conn.getresponse()
    response_time = time.time()
    conn.close()
    transfer_time = time.time()

    self.custom_timers['request sent'] = request_time - start
    self.custom_timers['response received'] = response_time - start
    self.custom_timers['content transferred'] = transfer_time - start

    assert (resp.status == 200), 'Bad Response: HTTP %s' % resp.status

Are these statistics available from a more high-level interface like urllib2? Is there high level library offering such statistics?
