It is actually possible (with fairly little work, last time I looked,
maybe it is already integrated in the kernel) to avoid all this kind of
thing from isolated CPUs.

But even then, note that the types of programs using the CPU for long
periods are obviously not going to be run on an average desktop system.
So the responsiveness argument is laughable. Responsive as defined how?
And in relation to what type of systems?
