Comment (by jinmei):

 trac2562 is ready for review.

 This actually required some more work than "confirm"; I at least
 needed to update noisy (and not precisely correct) log messages.
 I also updated the corresponding test case slightly.

 And, I also wasted my time by first trying to use the rpcCall
 interface just to know it currently doesn't work.  To prevent it from
 happening for others, I've added notes to the method's documentation
 even though it's not directly related to the subject of this branch.

 I'd also note that the revised code doesn't return NOTIMP.  Since auth
 now knows it has the authority for the notified zone, it should be
 more appropriate to handle this case just like it's not a secondary
 zone.

 I guess this probably needs a changelog.  Proposal:
 {{{
 594.?   [bug]           jinmei
         b10-auth now handles the case where zonemgr isn't running while
         handling an incoming NOTIFY message from other general errors
         in the communication with zonemgr.  Previously both cases were
         logged at the error level, and resulted in increasing noise when
         zonemgr is intentionally stopped.  Other than the log level
         there is no change in externally visible behavior.
         (Trac #2562, git TBD)
 }}}
