I am working on trying to get the leak-detection tools working in dhtml, which should help us verify that it is working. (I think Max had a tool that he could run in IE to do leak detection, but I don't know how to do that. If anyone else knows of a general AJAX leak detector, perhaps we could use that.)
I checked in my change, which definitely fixes the leak in swf, and
which I believe also fixes the leak in dhtml. We can do some more
testing in dhtml and tweak if necessary.
