:What's the point of SMP then? This would give us essentially a
:'single-threaded' process, since only one thread/process can be running
:at any one point in time. Arguable, this is still better than the
:current situation where if a thread blocks, the entire process blocks,
:but if we've got an idle CPU, why not allow another thread run in a
:second KSE on the idle processor?

:Think 'multi-threaded' applications. It's trivial to design a program
:where multiple threads are independant of one another.

Try reading my posting again, Nate, carefully. You missed the whole
