If I understand correctly, this is about spreading load on CPU, not cores. So dual core Intel
CPUs won't gain anything from this. But quadcore Intel laptop CPUs would, as they are still
not native QC but two dual-core sticked together.
On the other hand, AMD K10 family CPUs have very power-independent cores, so even dual-core
would benefit. AMD "Griffin" have split power-plane so I suppose this scheduling policy can
help lowering power consumption on it.
