def load_url(url, timeout): return urllib2.urlopen(url, timeout=timeout).read()
with futures.ThreadPoolExecutor(max_workers=5) as executor: future_to_url = dict((executor.submit(load_url, url, 60), url) for url in URLS)
for future in futures.as_completed(future_to_url):
url = future_to_url[future]
if future.exception() is not None:
