If people are concerned about performance, I benchmarked a 6-beta
kernel SMP versus UP on a socket 939 Opteron.

The performance characteristic for the parallel tests with CPU-eaters
and plain http streams in the background is different.

But there certainly is no slowdown that would make us look bad when
people use a SMP kernel on a one-processor machine.
