Strong? No. I think mine is better just because _if_ another CPU is busy
handling an interrupt that we're just now disabling, we'll just go on to
the next interrupt. Waiting for them all at the end is always more
efficient.

But does it really matter? No. In this case I think we've shut down all
other CPU's anyway, so the whole "serialize_irq()" should probably not
even be needed.
