"xargs -0" is not all that portable, either, and neither is "touch -h".
But since the t/perf stuff already depends on having GNU toolchain
anyway, I can be persuaded to believe that it is OK.
Do we know that this part runs much later than the staged files are
last touched, so that these uses of "touch" actually are effective
to make the paths stat-dirty? Otherwise, we may be just "touch"ing
them with the timestamp they already have after all.
Thanks.
