How does AP behave on HyperThreaded Processors?

AP treats a two-headed HT processor as two cpus in SMP. It assumes that each virtual processors has equal and constant throughput. This is true on true SMP machines, but is true on HT machines only when the system is sufficiently loaded to keep both pseudo-CPUs busy.
