title: Node.js script does not Exit
body: <p>Why does the following code not cause node to exit the process after running all 3 lines?</p>
  
  <pre><code>var monq = require('monq')
  var client = monq('mongodb://remote.db.com:27017/mydB')
  var queue = client.queue('users')
  </code></pre>
  
  <p>The script does exit if the 3rd line is not executed. </p>
