Why?  That's an odd request.  It's natural to want to reduce your priority
if you want other processes handled first, but an idle CPU is a wasted
resource.  You want it to be busy all of the time.

Scheduling and CPU priority are, by their very nature, operating system
concepts.  You will not find generic mechanisms wrapping them.
