title: Javascript performance problems with too many dom nodes?
body: <p>I'm currently debugging a ajax chat that just endlessly fills the page with DOM-elements. If you have a chat going for like 3 hours you will end up with god nows how many thousands of DOM-nodes. </p>
  
  <p>What are the problems related to <strong>extreme</strong> DOM Usage?</p>
  
  <p>Is it possible that the UI becomes totally unresponsive (especially in Internet Explorer)?</p>
  
  <p>(And related to this question is off course the solution, If there are any other solutions other than manual garbage collection and removal of dom nodes.)</p>
