Thermal zones are re-evaluated when a Notify comes in that says to do
so. Perhaps if "user_override" is set to 1, we should not re-evaluate
them. However, perhaps that should only be done for values the user
actually overrode.

There has to be a different solution Windows used. Maybe they ignore _crt.
