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)) { disable_real_irq(foo); timer_fake_irq_foo(); }
We know spoofing a shared irq is safe.
