 As far as I understand it at least BIND 9 doesn't treat REFUSED as a fatal
 error.  It will simply keep trying other servers.  I suspect other widely
 used recursive servers behave that way, too.  In fact, this type of lame
 is not uncommon (it can easily happen due to parent-child mismatch, for
 example), and if it triggered a perpanet failure we should have seen a lot
 of complaints.
