Yes, they are included. In fact, I would expect Debian BDB 4.2 to be much
more stable than whatever is available from Sleepycat, as a rule of thumb.

The dire days of BDB 4.2 royally screwing over your database in any non-joke
box are gone, fortunately.  As for BDB 4.3, I have no idea.

I would expect that to cause trouble with just about everything that uses
huge indexes and databases with BDB 4.3.   Or does it show up only in
OpenLDAP usage patterns (OpenLDAP is known to find all lurking bugs in BDB
that others never hit :-) ).

Not good.  That might mean a lot of trouble to get 4.3 out of sarge, and
revert all packages back to 4.2 :(
