title: nodeload.js - get this : (node) warning: possible EventEmitter memory leak detected. 11 listeners added.
body: <p>js to drive the testing of an helloworld express.js.
  There is nothing much in the sample express.js than sending back a hello world.</p>
  
  <p>I started my app.js 
  When I run the following command:
   <code>nodeload.js -c 100 -n 1000 http://xxx:</code>8082</p>
  
  <p>I got this warnings all over the place; warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.</p>
  
  <p>Then it completed with some statistic, however  many stack traces were dumped with the node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.</p>

  <p>Is this the nodeload issue? Or the sample hello world issue?
  People mentioned about <code>process.setMaxListeners(0)</code>.
  But that does not resolve the issue for me when I set it in the app.js</p>
  
  <p>Please advise what is this warning complaining about?
  This is not a node.js issue?  How to resolve this?
  Thanks in advance.</p>
