I think the counters will still be useful for NUMA also. Is there a
performance hit here I am missing to having the per node counters?
Just want to make sure we are only wondering about whether or not we
are polluting the interface? Also since we plan to change the name to
vmstat instead doesn't that make it more generic in the future?
