Currently when string instruction is only partially complete we go back

What happens if rcx is really big? Going back into the guest gave
us a preemption point.
Two solutions. We can check if reschedule is required and yield cpu if
needed. Or we can enter guest from time to time.
I'd stick with the current solution, reentering the guest every page or so.
