New description:

 e.g. in the "example" zone,

 {{{
 child.example. IN NS child.example.
 child.example. IN AAAA 2001:db8::1
 }}}

 It rejects this setup (at the time of find()) due to this:

 {{{#!c++
 DatabaseClient::Finder::getRRsets(const string& name, const WantedTypes&
 types,
                                   bool check_ns, const string*
 construct_name,
                                   bool any)
 ...
     if (check_ns && seen_ns && seen_other) {
         isc_throw(DataSourceError, "NS shares domain " << name <<
                   " with something else");
     }
 }}}

 This is incorrect and should be fixed.

 I'm temporarily disabling tests in zone_finder_context_unittest due to
 this bug (in the work for #1608).  When this ticket is resolved please
 re-enable those tests too.
