    irqbalance nowadays rotates the timer interrupt every 10 seconds after
    some people complained that having it always on the same cpu penalized
    their HPC apps unbalanced. (they glued those tasks to each cpu). It's
    not a big deal (the irq rate isn't that high) and it does make things
    slightly more fair in the HPC case.
