title: Python requests timeout not suitable when sites stream
body: <p>The following works for 99.999% of websites but randomly found one for which it does not:</p>
  
  <pre><code>import requests
  requests.get('http://arboleascity.com',timeout=(5,5),verify=False)
  </code></pre>
  
  <p>I have filed an issue on the project.</p>
  
  <p><a href="https://github.com/requests/requests/issues/4276" rel="nofollow noreferrer">https://github.com/requests/requests/issues/4276</a></p>
  
  <p>Any suggestions or ideas?</p>
  
  <p>I am running this in <code>concurrent.futures.ThreadPoolExecutor</code> so I don't really want to add in something external like eventlets or signals. But open to anything that works well. </p>
