Not sure about the beta or RC versions, but 9.2.3 still will not
resolve queries when reloading the massive RBL zone file, which can
take 10 to 15 minutes to process on a slower server.

To work around the issue, we eventually had to set up a separate
instance of BIND that was authoritative for the rbl zone, and then
set up our main DNS servers to forward queries for the rbl-plus
zone over to the separate server.
