title: Task manager shows memory leak, but Heap snapshot doesn't
body: <p>I run heavy JavaScript every 5 seconds and task manager shows constant increase of memory usage. However Heap snapshot doesn't. If I stop the script, memory is cleared after about <strike>half a minute</strike> two minutes. </p>
  
  <p>UPDATE:</p>
  
  <p>If I leave the script for a long time, the memory increases until the browser crashes. 
  I also tried to run timeline test of chrome dev tools, and they also don't show the increase of memory usage, same as Heap snapshot. So I guess it's some kind of a leak, but I can't understand what is leaking.</p>
  
  <p>Another thing which I can't confirm, as I can't install previous Chrome versions is that I don't remember this happening on previous (&lt;24 Chrome versions). And IE10 runs this test without increasing memory. Could this be issue of new Chrome?</p>
