Description
Sieve is still showing multiple DOM leaks on page left, it's pretty easy to reproduce with the default sample page, and this only affects IE6.

The patch also introduces 'unload' event hooks described here that is required for this cleanup.

Based on my testing, it could hardly form a event handler cycle reference leak pattern, as we have well-established defense of this, and invalidate all the event listener doesn't reduce one single leak count.
Unfortunately I was not unable to figure out where exactly comes the leak but did find where to dereference to eliminate all the leaks - releasing our dom wrapper's '$' reference does the trick.
