thanks for testing it! I was quite worried about your setup - two tasks using up 50%/50% of CPU time, pitted against a kernel rebuild workload seems to be a hard workload to get right. > [...] (I know a trivial way to cure that, and this framework makes > that possible without dorking up fairness as a general policy.) great! Please send patches so i can add them (once you are happy with the solution) - i think your workload isnt special in any way and could hit other people too.
