------- Additional Comments from Alexey Proskuryakov <ap at webkit.org>
This makes us faster than Firefox 2, but still slower than Firefox 3 beta (13.5
ms on my machine vs. 16 ms and 10 ms). Results on other benchmarks (such as
<http://www.andrewdupont.net/test/xpath/>) are also decent now, though not
always stellar.

I intend to close this bug after this lands, and to pause working on XPath
optimization during the stabilization period.
