Any BDB hackers around that know the background behind this?
The question is: Why isn't the base revision properly saved in the txn when the
HEAD revision is a no-op commit?
I'm guessing that we safe something else and then accidentally fetch the last
modified revision of that and use it as the BASE revision of the transaction.
