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.

(Don't confuse with 'rbldns')
