  3. Default to number of CPUs, which is what a lot of other threading
     in Git does. Unfortunately getting that from the shell is
     non-trivial. I'm OK with $(grep -c ^processor /proc/cpuinfo), but
     people on non-Linux platforms would have to fill in their own
     implementation.

How about $(getconf _NPROCESSORS_ONLN)?  That's what Linux's
scripts/coccicheck uses (apropos of a recent discussion :)).

Thanks, that's certainly less gross than grepping /proc/cpuinfo. getconf
is POSIX, but _NPROCESSORS_ONLN is not. According to [1], it works on
Linux and macOS, which is probably a reasonable start, though. This is,
after all, a script aimed at developers, and the worst case is that we
default back to 1.
