This improves the situation (the highest spike I saw so far was 2,000
interrupts per CPU per second), but doesn't get it back the way it
ought to be (apart from the spikes, as with the original version of the
patch, interrupt activity is also generally too high, very erratic, and
even during the more quiet periods doesn't go down to the original
level).
