Thanks!

Don't pull my code just yet.  I'm continuing to work on it.  I've
figured out a significantly more memory-efficient layout for the
trie nodes (and a few other improvements).

I should have the improved code ready for inspection in two or three
days.

I agree that the master-dump for ipv6 is not particularly useful to
the end user.  It has been helping me during debugging of my code,
however ;-)

PS: Thank you for all your work on rbldnsd.  Where would we be without it?
