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.
