No no, I'm saying that giving certain tasks special dispensations
effectively elevates them.  Temporarily or otherwise, they play by
different rules, will block more deserving tasks, and it's not cut and

Is it a clear win to make say some kworker or other global asset wait
when it could have preempted and been gone in usecs?  Nope.
