-	  Not on windows, because line buffering does not work there.
-
-9 September 2009: Wouter
-	- Fix bug where DNSSEC-bogus messages were marked with too high TTL.

-o SOA records in negative cached answers for DS queries.
-  The current unbound code uses a negative cache for queries for type DS.
-  This speeds up building chains of trust, and uses NSEC and NSEC3
-  (optout) information to speed up lookups.  When used internally,
-  the bare NSEC(3) information is sufficient, probably picked up from

-  queries are performed to get the data.
-
-o Parent and child with different nameserver information.
-  A misconfiguration that sometimes happens is where the parent and child
-  have different NS, glue information.  The child is authoritative, and
-  unbound will not trust information from the parent nameservers as the
-  final answer.  To help lookups, unbound will however use the parent-side
-  version of the glue as a last resort lookup.  This resolves lookups for
-  those misconfigured domains where the servers reported by the parent
-  are the only ones working, and servers reported by the child do not.
-
-o Failure of validation and probing.
-  Retries on a validation failure are now 5x to a different nameserver IP
-  (if possible), and then it gives up, for one name, type, class entry in
-  the message cache.  If a DNSKEY or DS fails in the chain of trust in the
-  key cache additionally, after the probing, a bad key entry is created that
-  makes the entire zone bogus for 900 seconds.  This is a fixed value at
-  this time and is conservative in sending probes.  It makes the compound
-  effect of many resolvers less and easier to handle, but penalizes
-  individual resolvers by having less probes and a longer time before fixes
