title: Supervisor socket error issue
body: <pre><code>$ supervisorctl reread
  error: &lt;class 'socket.error'&gt;, [Errno 111] Connection refused: file: /usr/lib64/python2.6/socket.py line: 567
  </code></pre>
  
  <p>I'm trying to configure supervisor on my production system, but am hitting this error. The supervisor log file is empty.</p>
  
  <p>When I just type <code>supervisorctl</code>, it complains:</p>
  
  <pre><code>http://localhost:9001 refused connection
  </code></pre>
  
  <p>Nothing is currently listening on port 9001, AFACT: <code>lsof | grep TCP</code> returns nothing.</p>
