The problem is that a loaded 2-way machine is only slightly more expensive
than a 1-way, and current trends indicate that 4-ways will be increasingly
common. It isn't a question of 1 big 4-way vs 4 1-ways, but of
what you can get of out $Xk worth of hardware. The current sweet
spot is often some number of 2-ways, and if for your app the OS doesn't
scale it can make that OS less economical by comparison.
