title: requests process hangs
body: <p>I'm using <code>requests</code> to get a URL, such as:</p>
  
  <pre><code>while True:
      try:
          rv = requests.get(url, timeout=1)
          doSth(rv)
      except socket.timeout as e:
          print e
      except Exception as e:
          print e
  </code></pre>
  
  <p>After it runs for a while, it quits working. No exception or any error, just like it suspended. I then stop the process by typing Ctrl+C from the console. It shows that the process is waiting for data:</p>
  
  <pre class="lang-none prettyprint-override"><code>  .............
     httplib_response = conn.getresponse(buffering=True) #httplib.py
     response.begin() #httplib.py
     version, status, reason = self._read_status() #httplib.py
     line = self.fp.readline(_MAXLINE + 1) #httplib.py
     data = self._sock.recv(self._rbufsize) #socket.py
  KeyboardInterrupt
  </code></pre>
  
  <p>Why is this happening? Is there a solution?</p>
