I think this may have caused a ~12% improvement in dom_perf/CreateNodes. Hard to tell. http://trac.webkit.org/changeset/136334 seems more likely.

Hmm, that change is going to really skew our perf benchmarks that create nodes because they all run inside the 10 second window. They don't represent what goes on inside a real webapp which you keep open for a while.

I think that this change is causing this web page to assert: http://www2.macleans.ca/2012/11/04/tarnished-silver-assessing-the-new-king-of-stats/
