i asked todd miller about this, and he says he interprets "current load
average" to be the 1 minute average (closest to now). i think that's a
reasonable interpretation, so i don;t think we need to change the
description.

having said that, uvm(9) talks about "current load averages" (plural),
so i need to find out if that's something worth tweaking.
