Scheduling and hyperthreading GSoC results so far

Mihai Carabas posted some benchmarks for his work with the DragonFly default scheduler and hyperthreaded CPUs. ┬áThe end result, for those who don’t like number analysis, is that CPU-dependent speeds are reliably constant because tasks are being evenly scheduled across available CPUs.

(Well, CPU threads, since this is hyperthreading, but you get the idea.)
