Thanks for doing this!

For what it's worth, I've been running plocate locally since it was
brought up to the list earlier this year(?), and while it's much faster
I have one small complain: the indexing phase is way too power-hungry.

This is not actually a complain about power draw (there's the onACpower
conditional as rightfully pointed out), but about kicking in the fans
a few times a week (because of the randomized delay, it happens when I'm
at desk regularily) when I'm at desk.

I see now that it has IOSchedulingClass=IDLE but nothing equivalent
about CPU, but I don't think that'll help: if the computer is mostly
idle it'll still use all the cores (and increase cpufreq automatically)
for long enough to heat up and make the fans kick in.

I don't think there is a laptop friendly scheduler that says if this
task is niced then keep the cpufreq at its minimum, is there?
I've been manually fiddling with my cpufreqs' scaling_max_freq just low
enough to not trigger the fans but it sounds like overengineering to
me...


(feel free to ignore me, I'm overall very happy about this change)
