    I'd rather leave the handler as a handle which could return
    IRQ_NEEDS_HANDLING to get a separate thread_fn called. This seems more
    intuitive and means less mess in the fastpath.

    Maybe IRQ_NEEDS_HANDLING might better be named IRQ_THREADED os similar,
    but that's really getting into nitpicking..
