Hmm never heard the term "CPU compilation" before. Anyhow, you are right
that users could notice depending on the memory situation. On my system
(which has enough RAM) if I do 'qsched -l 16 make zlilo' then I would be
surprised if anyone noticed a slowdown.

Yes. But it's only for compatibility - use 'qsched' when possible.
