title: queue ImportError in python 3
body: <p>I am not sure why I am getting this <code>ImportError</code>. <code>queue.Queue()</code> is in the documentation.</p>

  <p>I am using it in a function like so:</p>
  
  <p><code>node_queue = queue.Queue()</code></p>
  
  <p>error:</p>
  
  <pre><code>Traceback (most recent call last):

  <p>Line 5 is <code>import queue</code>:</p>
  
  <pre><code>#!/usr/bin/env python3
