Thanks, will try that.

Ugh, actually I misread the size of the zonefiles:
They are 2x about 55MB thats about 110MB in total.
Should still fit in memory though.
AFAIK, rbldnsd has a somewhat optimized zonefile format.
When converted to BIND format, a 55MB rbldns zonefile
grows to 286MB.
I guess, rbldnsd generates TXT records dynamicallly
while BIND needs them in the zonefile.
