My memory is fuzzy, but I'm pretty sure I''ve seen macs (macos) enter
sleep in the middle of a huge compilation.  My impression has been that
entering sleep is about timeouts from keyboard/mouse and the implied
human.

Systems have all sorts of background processes, like syslog and cron.
So this may well be true, but it doesn't seem obviously sensible.

Hence my notion of something specific that can be looked up and the
details read about.
