title: Closing "Python Requests" connection from another thread
body: <p>To close the application as soon as possible, can I interrupt requests.post call from another thread and have it terminate connection immediately ? </p>
  
  <p>I played with adapters, but no luck so far:</p>
  
  <pre><code>for ad in self.client.session.adapters.values():
      ad.close()
  </code></pre>
