+8 January 2010: Wouter
+ - Fix for parent-child disagreement code which could have trouble
+ when (a) ipv6 was disabled and (b) the TTL for parent and child
+ were different. There were two bugs, the parent-side information
+ is fixed to no longer block lookup of child side information and
+ the iterator is fixed to no longer attempt to get ipv6 when it is
+ not enabled and then give up in failure.

7 January 2010: Wouter
- Fixup python documentation (thanks Leo Vandewoestijne).
