> Interestingly enough, when I first did a niave implementation of this fastNextRenderer, it disappeared off of the peacekeeper shark sample, but the peacekeeper numbers didn't get any better.  Making me wonder if shark is leading me astray.

Someone who wanted to work on this bug could and *should* confirm that, by simply replacing the nextRenderer() call in createRendererIfNecessary with "0" and re-running peacekeeper.  I saw no change in time on my machine, *despite* the previously 25% of the sample which was in nextRenderer() disappearing.   However it's possible I misread the peacekeeper numbers.  My current theory is that Shark's 25% attribution to nextRenderer() is a bug.
