Did you not consider using rbldnsd for your DNSBL? Update it from
MySQL as often as once per minute from cron (it's designed to properly
handle in-service updates of the zone data) or perhaps on a trigger if
your MySQL is new enough.
Way better then BIND for this job, way easier to write the zone files,
much lower memory usage, faster, etc etc.
