-/**
- * @class Ext.util.TaskRunner
- * Provides the ability to execute one or more arbitrary tasks in a multithreaded manner.  Generally, you can use
- * the singleton {@link Ext.TaskMgr} instead, but if needed, you can create separate instances of TaskRunner.  Any
- * number of separate tasks can be started at any time and will run independently of each other.  Example usage:
- * <pre><code>
-// Start a simple clock task that updates a div once per second
-var task = {
-    run: function(){
-        Ext.fly('clock').update(new Date().format('g:i:s A'));
-    },
-    interval: 1000 //1 second
-}
-var runner = new Ext.util.TaskRunner();
-runner.start(task);
-</code></pre>
- * @constructor
- * @param {Number} interval (optional) The minimum precision in milliseconds supported by this TaskRunner instance
- * (defaults to 10)
