It will take a couple of days, at best, as I'll be travelling.
Any earlier C-only test didn't show a clear difference either way.
The patches are "winning" even if the immediate performance difference
is a wash because they'll allow us to track column numbers at little
or no extra cost.
Yes, I agree -- if there is no performance downside, then there is some
upside. I just want to check that there is indeed no downside, at least.
