title: wxPython: Using EVT_IDLE
body: <p>I defined an handler for <code>EVT_IDLE</code> that does a certain background task for me. (That task is to take completed work from a few processes and integrate it into some object, making a visible change in the GUI.)</p>
  
  <p>The problem is that when the user is not moving the mouse or doing anything, <code>EVT_IDLE</code> doesn't get called more than once. I would like this handler to be working all the time. So I tried calling <code>event.RequestMore()</code> at the end of the handler. Works, but now it takes a whole lot of CPU. (I'm guessing it's just looping excessively on that task.)</p>
  
  <p>I'm willing to limit the number of times the task will be carried out per second; How do I do that?</p>
  
  <p>Or do you have another solution in mind?</p>
