title: Keep a task grunt task open
body: <p>I have a grunt task that kicks off a socket-io server among other things.</p>
  
  <p>I have found a way of keeping the task 'open' (ie, not exiting straight away on the command line) by running the 'watch' task right after it. e.g</p>
  
  <p><code>grunt.registerTask('default', ["mytask", "watch"]);</code></p>
  
  <p>But this requires me to fill in some dummy data in the Gruntfile such as. </p>
  
  <pre><code>// Not needed...
  watch: {
    files: "test/*"
  },
  </code></pre>
  
  <p>So is there a way to keep my task running without having to use the watch task along with it?</p>
  
  <p>Thanks</p>
