This time it uses common kvm functions to sleep the guest.

Looking much better now, with just a few minor issues to correct. With these
patches applied, about how much CPU *does* an idling guest consume?

By the way, you don't explicitly *unset* MSR[WE]. I think this works
implicitly because of the way we deliver interrupts; could you add a comment
explaining that?
