Re: CPU report in first line of "vmstat 1" is meaningless

Maybe only blank it out on 32-bit machines?  It's a long, and a 64-bit
cp_time value essentially won't roll over (at 1 billion increments per
second it will roll over in 500 years; we currently increment 133 times per
second, I think).  If the value can be calculated accurately, it should be
printed.
