This is a good point.  Multiuser, multitasking OS's like Unix were
designed to keep the *machine* productive, occasionally at the expense
of wasting an interactive user's time.  That made sense when hardware
and machine time were (or seemed) more expensive than people's time.

Now it's the other way around, and the Mac is a good example; its goal
is to keep the user productive, not to keep the processor busy.  (In
fact, processors on single-user machines are "idle" virtually ALL the time.
But who cares?  As the old saying goes, "Better to have it and not need it
than to need it and not have it."

So in the mad scramble to add features of multiuser operating systems
to single-user machines, it's important to remember that some of those
features were designed with different goals in mind, and those goals
weren't necessarily user-friendly!

It would be interesting to have a Mac operating system which allowed a user
to choose either cooperative or competitive multitasking at any time.
(By clicking a button, of course!  Instantly toggle between MultiFinder and
A/UX-with-a-MultiFinder-interface, maybe?)

I wonder which mode people would end up using most, and for what reasons?
