A UP HT box you mean? That shouldn't be capable of running multiple make -j10s without some noticable effect. Apart from looking impressive, there is no point in having 30 cpu heavy things running with only 1 and a bit processor and the machine being smooth as silk; the cpu heavy things will just be unfairly starved in the interest of appearance (I can do that easily enough). Please give details if there is a specific issue you think I've broken or else I wont know about it.

They're not; the improvements should affect fairness on SMP as well and although interactivity is what I'm addressing on the surface, fairness is the real issue.
