OK, I'm looking at three patches to merge in first - the two I posted
today and the input randomizing patch you had posted earlier. Once
they're in we could evaluate this as an enhancement on top of those
changes. All of this obviously means that we need someone other than
you and me to review these three patches. Does that sound OK?
