This leak still exists in 1.3.2 :(

I have discovered what I believe to be a pretty serious memory leak in the Request class. My site has long-running scripts with large data payloads. So, a user may leave the page open for days at a time without reloading the page. During that time, the site makes many AJAX requests to my server. I’ve noticed that my browser (all browsers I’ve tested – Chrome, Safari, and Firefox) degrade pretty quickly and consume copious amounts of memory within a few hours.
After several days of debugging, I have identified that it’s a problem with the Request class in MooTools. Here is a sample script to recreate the problem:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/mootools/1.3.0/mootools.js"></script>
</head>
<body>
<script type="text/javascript">
document.addEvent("domready", req);
function req() {
new Request({
url: "index.json", // a large JSON-encoded file, ~250k
onSuccess: success
}).get();
}
function success(resp) {
setTimeout(req, 1000);
}
</script>
</body>
</html>
