I don't think it does. There are two pieces to the problem

        a) Not dying horribly
        b) Handling it elegantly

b) is driver specific (NAPI etc) and I think well understood to the point
its being used already for performance reasons

a) is as simple as

        if(stuck_in_irq(foo) && irq_shared(foo))

We know spoofing a shared irq is safe.
