I'm thinking for the benefits that low latency audio applications will
have from preemption of running task in favour of the waiting task just
at end of interrupt handler execution (instead of end of time slice).

I don't believe that such a mechanism is already in place in linux
kernel but I may be wrong.

If we couple this with Robert Love full preempt patch we should have a
reliable, "almost" warranted very low latency also during very high load
condition (and also on UP).
