One of our tests wasn't passing and we were debugging and
debugging only to be left scratching our heads.

It turns out that labels in RDATA are terminated by RLENGTH,
not by null (as most labels are), but since generally CLASS
begins with 0x0001, which looks like a null terminator... in
almost every case, it tooks us forever to figure it out.
