information can be discerned via node parent pointers.
533. [func] Incorporated name hashing into the RBT database to
improve search speed.
There is still evidence of a bug with regard to bitstring labels. It shows
up in bin/test/rbt/t_rbt -x -t 4 when the assertion at lib/dns/rbt.c:1631
is uncommented -- essentially a bitstring node's location in the hashtable
is not getting properly updated at some point. This shouldn't affect
searching, because a bitstring label as the parent of a new level will
generally cause the standard old binary search to be done. I will be looking
at this more closely in the very near future.
