Will the OS schedule tasks smartly to virtual CPUs? The extra hyperthreads
just aren't as good as a real CPU, so the scheduler should take that into
account. How about processor affinity, which BeOS didn't have? That
should cut down on CPU caches being wasted by unnecessary task movement
between CPUs. At least with Haiku, if it's not in there then it is
possible to add it!
