It's close to SMP, but if you have a dual K8 with single-core processors, you can set LOGICAL_CPUS=0. For testing, you could do that with dual-core processors to disable the siblings... right? I guess it comes down to the fact that we should document it. If we can't define it succinctly on the mailing list, the chance that we're going to be able to come up with a descriptive CONFIG_ name is small.
