I think Rusty would be best placed to describe his work here once he
returns from his Honeymoon, but I do know he spent a lot of time
ensuring that before tdb2 was enabled in the top level that all users
were converted away from checking errors with == -1. (Loosing the work
done there was the bit-rotting I was concerned about if we dropped tdb2
for 4.0, as you proposed on IRC).
I will also note that we are in this unfortunate transitional situation
at least in part because the last time changing to tdb2 was discussed
(September 2011) it degenerated into a discussion of our build systems.
None of that discussion turned to what seems now to be such a
controversial issue, that is the manner and length of the transition.
I'm not happy with the way tdb2 has gone either, and I know from
personal experience (working with multiple krb5 libs and build systems
in particular) how much this kind of duplication can cost. But I would
be far happier with this discussion if we tabled it until we know Rusty
is back at work, online and able to defend the efforts that he has taken
