By my reading that does not give what we want here.  In a machine with
eight CPUs and all are down but CPU7, then num_online_cpus() will
return 1.

In the light of the nonlinear/hotplug CPU work in 2.5, I think looping
up to NR_CPUS and checking cpu_online really is the right way to do
it.  (But I know much less about it than other people.)
