Adam and I have now reduced the test case to:

<pre id="console"></pre>
<script>
var startTime = new Date;
layoutTestController.dumpAsText();
function log(message)
{
   
document.getElementById('console').appendChild(document.createTextNode(message
+ '\n'));
}
var req = new XMLHttpRequest;
req.open("GET", "http://localhost:8000/xxxxx", false);
req.send();
log("Time: " + (new Date - startTime));
</script>

See the instructions for running it under DRT above.

If you change this to use same-origin (127.0.0.1), we don't hang.  But the test
as is will hang for about 1 second every 50 requests or so.
