------- Additional Comments from Alexey Proskuryakov <ap at webkit.org>
Committed revision 20102, clearing the review flag.

It's particularly inefficient that NodeVector is a vector of RefPtrs. It has to
hold onto its nodes because Attr nodes usually don't have any other references.
Of course, re-creating Attr nodes all the time doesn't help, too.
