Sure, I don't doubt the high level theory.  Does anyone have numbers to
show it's relative effect in practice?  That'd be interesting.

Well, that's debatable.  My only point, though, is that there are higher
priority things that we should get to first because they affect *everyone*.

If the lack of external journals makes you sad, well, I'm sorry to hear
that.  We certainly wouldn't turn away patches if someone got to it
before us.

So noted.  I'm curious, though.  What sort of NVRAM hardware do you have
in mind?
