I'd rather see different interrupt sources run on different CPUs
initially, which would help fairness a little bit, and should be
more optimal with big interrupt loads.
0: xxx1 0 0 0
1: 0 xxx2 0 0
2: 0 0 xxx3 0
3: 0 0 0 xxx4
This would delay the need for interrupt balancing in the case where
2 or more interrupts are heavily used.
