Hi Kevin -

Thanks for working on this! Given that the motivation / direction has already been discussed and that this is off by default, I see no reason not to commit this ASAP. We can test / benchmark / evolve it faster in trunk vs. privately.

I'm cc'ing some of the people from the bug report discussions just so they are aware of this pass.
