Exactly. Normal interrupts we can handle. Having CPU completely
disappear for unkown time periods we can't, and will need to.
But that is just what a interrupt is.
Interrupts tend to be reasonably short though.
Steal time can be several hypervisor/host time slices long.
As an aside, normal interrupts *are* accounted for separately
in /proc/stat, so why not steal time too?
