urlfetch.make_fetch_call(rpc[-1],
    'http://stackoverflow.com/questions/3639855/what-happens-if-i-call-more-than-10-asynchronous-url-fetch'
    )
for r in rpc:
    response = r.get_result()
logging.info('Response: %s', str(response.status_code))
Is there a limit on the number of asynchronous urlfetch calls I can run simultaneously?
