-- * status == -1: set to "disabled" with no TTL
-- * status == -2: not set, meaning that is was set before but expired
-- * status > 0: set to "valid", with a TTL

-- In the case of status == -2, we set the status to "pending" with
-- 30 second ttl. During this time, the process which got status == -2
