runsvdir has used 1m 55s over a bit under 5 days. The runsv instances are way less (but then they have no reason to wake). Load average is 0.00.

That sounds sensible on a desktop. In my case the motivation is to trim a source of power draw for an image that's going to run on a battery-powered device that will be awake but idle a lot of the time. Why Linux? Pretty much familiarity & tooling, if power is ok then I get to have my cake and eat it too.
