Maybe swap was necessary back in the days when memory was really tight, but it seems like a terrible idea now. Especially since the scheduling is completely oblivious to swap AFAIK, which means that a heavily swapped system will spend most of its timeslices just swapping program code back into memory. It's the worst kind of thrashing.
