Huh? Where did you read this? I have hundreds of master zones on some of my
servers, and there are folks who have 10's of 1,000's or even 100's of 1,000's
of master zones on a single box. When you get up to that level, reloads get to
be a pain (unless you are using multi-threading BIND 9), but normal operation
shouldn't really suffer.

Define superdomain.com as a master zone on the same server. Note however that
the "superdomain.com" name itself (as opposed to "www.superdomain.com",
"ftp.superdomain.com" or any other name in the zone), will need to be 1 or more
A records. It can't be a CNAME, due to the infamous "CNAME and other
data" rule.
