No, we don't.  And it wasn't an easy decision to make, but after a week
of benchmarking and optimization it was clear that it needed be done.
The complex approach using expanding nested hashtables didn't win
enough:

(1) Since ntdb is a standalone library, it needs to scale down like tdb
    does, and the complicated hashtable nesting didn't do that.

(2) It effectively rips out the tdb2 nested hashtable implementation in
    favor of a slight variant of the tdb1 version.  It cut almost 300
    lines off hash.c, and 600 lines in total.

Hope that helps,
Rusty.
