title: Using httplib2 in python 3 properly? (Timeout problems)
body: <p>Hey, first time post, I'm really stuck on httplib2. I've been reading up on it from diveintopython3.org, but it mentions nothing about a timeout function. I look up the documentation, but the only thing I see is an ability to put a timeout int but there are no units specified (seconds? milliseconds? What's the default if None?) This is what I have (I also have code to check what the response is and try again, but it's never tried more than once)</p>
  
  <pre><code>h = httplib2.Http('.cache', timeout=None)
  for url in list:
      response, content = h.request(url)
      more stuff...
  </code></pre>
  
  <p>So the Http object stays around until some arbitrary time, but I'm downloading a ton of pages from the same server, and after a while, it hangs on getting a page. No errors are thrown, the thing just hangs at a page. So then I try:</p>
  
  <pre><code>h = httplib2.Http('.cache', timeout=None)
  for url in list:
      try:
          response, content = h.request(url)
      except:
          h = httplib2.Http('.cache', timeout=None)
      more stuff...
  </code></pre>
  
  <p>But then it recreates another Http object every time (goes down the 'except' path)...I dont understand how to keep getting with the same object, until it expires and I make another. Also, is there a way to set a timeout on an individual request?</p>
  
  <p>Thanks for the help!</p>
