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? > I can't imagine how > we could possibly run KSEs belonging to the same process concurrently > anyway. Think 'multi-threaded' applications. It's trivial to design a program where multiple threads are independant of one another.
