Joe, "I think the key to a successful implementation of Hyperthreading is to know when.."

There might be a simpler explanation - caches. In true
2-CPU architecture the caches are truly independent,
and the OS has certain ideas now to use them. In pseudo
two-CPU, it might cause severe cache conflicts, with
massive increase in off-chip traffic. To avoid this,
I guess, a total OS kernel rework is necessary.

Regards,
