This is an interesting question, would this actually occur. Or put
another way, if I have a broken (or maybe not broken) driver that
returns a DDI_INTR_UNCLAIMED even though it should/could have
processed the interrupt. Will it continue to be called, till it (or
some other isr) claims the interrupt? Or will it just be tossed?
