Details
Save the HTML below into a file and view it with Mozilla. Mozilla goes into an
infinite loop which it never exits. CPU activity goes through the roof and the
UI is unresponsive and must be killed.
<html>
<head>
<title>Death by Javascript!</title>
</head>
<body>
<p>
<script language="JavaScript">
document.write("Script running");
while(1 > 0) ;
document.write("Script complete");
</script>
</p>
</body>
</html>

This is similar to bug 13350 except that there's no issue with GC here, it's
just that the browser locks up due to the infinite loop. Nav 4.7 keeps the UI
alive at least.
