entries, not freed ones.  tdbutil shows nothing on the "free list".
Identical results are showing on our Linux server.

Something is going wrong in the process which is prunes out old entries,
preventing them from being freed in clear_unexpected() -> traverse_fn () ->
tdb_delete() -> do_delete() .  The code in do_delete() checks to see if
someone is traversing that record (apparently always true in this instance)
and marks it "dead" rather than really deleting the entry.  Thus the file
grows indefinitely.  Someone who understand the tdb logic may offer a simple
