Why wouldn't we just leave it out then? Putting it in when the one
platform we've tried it on shows a regression makes no sense. We
shouldn't include it and then remove it if someone can prove it's bad;
we should only include it in the first place if we have good
benchmarks showing that it is good.
Does anyone have a big Windows box they can try this on?
