Comment (by y-aharen):

 I haven't considered the less efficiency of ZoneFinder::getOrigin() as it
 is called while processing queries in addAuthAdditional() and addSOA(). Is
 there another approach to get which zone is the nearest ancestor to qname?
 If there is an efficient method to get zone identifier of ZoneFinder other
 than zone name, I'll use it.
