------- Additional Comments from Elliott Sprehn <esprehn at chromium.org>
Did performance testing and removed original speculative optimizations in favor
of ones that actually seem needed. There's no observable slowdown now, and
there's a 15% improvement on Parser/textarea-parsing.html in addition to the 5%
improvement for node lists (and treeScope)
