Creating an element leaks memory in ie7

Description
when i run the appended html file in ie7, the browser reserves about ~150mb. when running the page without executing the jQuery("<div...) memory usage goes back to ~75mb. (note the div is not appended to the document or referenced in any way).
in firefox memory usage spikes a little bit when loading the page but goes back to a normal level.
<html> <head> <script src="http://code.jquery.com/jquery-latest.pack.js"></script> </head> <body> <script> jQuery(document).ready(function(){ for(var i =0; i<10000; i++){
jQuery("<div></div>");
} }); </script> <div id="debug"> </div> </body> </html>

Since I stumbled upon this bug let me respond to it properly. :)
I'm not sure what you expect jQuery to do here. You've created new elements but haven't done anything with them. They are in limbo in IE and the IE GC can't get to them. You need to do something with them... either append them to the DOM or null them out when you are done with them.
this is fixed in r6310
