    per handler is the right approach (that way, if one dies, all other
    interrupts will likely keep working)

    now.. normally an interrupt only goes to one cpu, so effectively it is
    per cpu already anyway

    we should however make the irq threads follow the affinity masks of the
    irq... that'd be an easy add-on and probably worthwhile.
