Perhaps my judgement is too colored by benchmark(et)ing, and desires to 
have repeatable results on things like neperf, but I very much like to 
know where my interrupts are going and don't like them moving around. 
That is why I am not particularly fond of either flavor of irq balancing.

That being the case, whatever is out there aught to be able to be 
disabled on a running system without having to roll bits or reboot.
