[Gllug] Forcing CPU and Mem limits on a process

It still does: it's just that if more than one entity is contending for
the CPU, and others can potentially take CPU time without exceeding
their usage percentage, and you *are* exceeding your usage percentage,
your usage drops until it's at no more than that percentage again.

(This isn't very useful unless you want to *ensure* that it gets at
least that much CPU time: otherwise, relative priorities like Unix
already has do the job perfectly well.)
