  <p>Wait, what?!? Does this mean we've got multi-threaded parallel JavaScript code execution (outside of web-workers) in IE9?</p>
  
  <p>I'm thinking this is just a bad marketing gimmick but would like to see some more info on this. Maybe they mean different browser windows/tabs/processes can utilize multiple CPUs?</p>
