Ok, then, I'm working on the code with the new approach.
My fear was that some CPU 7 is taken down, but vcpu.cpu remains 7 (not set to
-1). If cpu 7 nevers comes up again, it's not a problem because when we run
the same vcpu again on a different cpu, it's not 7 so we do what needs to be
done on CPU switch. But, what if CPU 7 does come up again later, and we find
ourselves running again on CPU 7, but it's not the same CPU 7 and we don't
know it? Is this case at all possible?
