Yes but in the later case, real hardware must re-send the pending
interrupt after it is unmasked (that's the spec). We would just lose it.
That's a different matter. We need to buffer the interrupt pending bit,
and a way for userspace to either query that buffer or have a
conditional injection (inject_if_pending).
