  35     Test that media players aren't leaked on error.
  36     Load this page and verify the number of threads used by the browser doesn't
  37     seem unreasonable (e.g. chrome uses 4-5 threads per video tag so staying
  38     under 100 threads is "success", since this instantiates 20 &lt;video&gt; elements).
