the DNS_DB_NOEXACT flag. This means that the resolver will start look for the
key at or above the parent zone, and will return the key set from the parent
zone if key sets are present in both the parent and child.
DNS_R_DELEGATION, don't use the domain & ns set found by dns_db_find().
This means that a recursive server will not immediately ask the child zone
for a key set at the apex; the resolver will determine who to ask.
algorithm to more closely follow RFC1035, so that root servers will
provide a more complete set of name server glue addresses in ccTLD
referral responses.
For non-referral responses, the server no longer uses glue as
additional data.
For referral responses, the servers now looks for glue A/AAAA/A6 RRs
in the zone where the NS RRs reside, even in the case where this is
different from the zone where the A/AAAA/A6 RRs would have resided had
they been authoritative data.
A6 chains included as additional info may not yet fully follow these
rules.

NULL. It appears that zone maintenance can occur when the zone is shutting
down and the view pointer is NULL. We don't want to do zone maintenance in
this case.
isc_socket_sendto() calls that did not yet have their
completion events posted, so it could (rarely) end up
destroying the query context and then want to use
it again when the send event posted, triggering an
assertion as it tried to cancel an already-canceled
query. (RT #77)
... so now the resolver counts the number of outstanding isc_socket_sendto()s
and only destroys the query context when there are no more.
305. [bug] When reloading the server with a config file
containing a syntax error, it could catch an
assertion failure trying to perform zone
maintenance on tentatively created zones whose
views were never fully configured and lacked
an address database.
