I may want an IO bound process to have a lower IO priority than other processes, but that doesnt mean I necessarily want it to have to wait for CPU time when it is ready for it. By definition an IO bound process is not going to be competing much with other IO bound processes for CPU time, so it doesnt seem to make much sense to force them to use CPU priority for their IO contention, when that will put them at a disadvantage relative to CPU bound processes; it seems reasonable for all IO bound processes to have a high CPU priority, as has traditionally been the case.
