Maybe the software scheduler should already schedule
optimally, be it preemptive SJF or whatever, anyway so only
possibility to reduce CPU temperature that way is to schedule
less anyway - also backwards, since computing is like the
"king" here it means if heat is a problem, it's not on our
side of it really.
