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.
