Doing it as a Makefile will *increase* them -- there'll be
overhead of at least one fork-exec per Makefile rule, i.e. one
per test, that isn't there in the current one-big-shell-script
scheme.

I'm *not* arguing against Paolo's idea -- it sounds rather cool
-- just pointing out one of the costs.

The acronym for "the powers that be" differs by only one letter
from that for "the pointy-haired boss".
