Because the OS was written from the ground up as multi-user, that's not
really a fair comparison. The items I referred to fire up when the
machine
loads the OS and nothing can or will stop that. They are all elements of
a OS that supports multi-job environment. To compare a single Intel CPU
to a machine that has many "processors" just can't be done and that was 
my point. 

I have been using PC's long before they got to be a commodity based
product.
(Late 70's early 80's)

I am well aware of what they can and "can't" do. If you have ever seen
any NT machine with a single processor running more than one job at a
time, you and I don't have the same concept of multi-processing. Task
swapping is NOT multi-user. It creates the illusion of multi-user but 
it's not the same. W/xx or NT(Nice Try) remain what they are and in
fairness to them, should not be compared to a real OS.
