In a page close CC of the HTML5 spec, running unlink on the nsDocument takes a lot of time, because it isn't using the lazy content blaster.

On a TechCrunch page close CC, unlinking the document takes 1.4ms according to my measurements.

The time is almost entirely spent unlinking the mChildren nsAttrAndChildArray, so if we could just unlink those incrementally that should solve this problem.
