Personally, any extra CPU burn bothers me. Maybe I am just
obsessive about that. Anyway, extra CPU usually does translate
into wall clock time, so optimizing sync would seem to be worth
the price of admission by that criterion alone. In general it's hard
to see why syncing fast and efficiently could ever be a bad thing.

I agree, not high priority. Not useless either. I see it more as a fit
and finish thing.

Daniel
