IF we ever see this as a real issue, we can either see it in the 
IRQ_PENDING flag, or we can mark such interrupts specially. So it would be 
solvable. That said, I haven't actually heard any real usage cases. Normal 
wakeup events are _not_ interrupts in the regular "device interrupt 
controller" sense.

So can you actually point to an explicit example of something where this 
is a real issue?
