  Log Message:

  rework ratelimit distributed queries

instead of adding -1 to the counter, use the cachedb_sub function exported by
the cachedb module. This prevents ratelimit counters from adding extremely
large values for some backends (ex: memcached).
Thanks go to Brett Nemeroff for reporting and testing.
