I think I like this best, since it won't require someone to notice they
have to add an explicit initialization if they add a new counter, as well
as saving us from memset'ing the entire struct, the majority of which
we'll initialize moments later. Just needs some documentation updates,
which I've done locally. Will rebuild, re-test, then hopefully get an
updated patchset out the door.
