One suggestion: There are several copies of "The reason a catalog zone is considered broken SHOULD always be communicated clearly to the operator (e.g. through a log message)." I think it would be better to put this into a central place, once (but I don't feel strongly).
Ack, done in commits 5e2d708 and 3848c55
For review once I processed all issues.
