The command seems to turn into an AXFR query, which isn't supported in strict
mode. I don't know if this behavior can be omitted by the pdns server code.
AXFR in strict mode returns FALSE - it doesn't throw an exception. Therefore I
also think that the pdns server shouldn't recreate the backend.
@Bert: Am I doing something wrong by returning FALSE?

Well, it doesn't crash but it does more than it should do.
