what if we just don't lock ever on delete, but if we still check lock to 
see if it's processed. at that point, the janitor knows that metric(s) 
is deleted, and since no one else is working on sack, any metricd that 
follows will also know that the metric(s) are deleted and therefore, 
won't work on it.
