dbnosync loses consistency after a system crash, and it loses the knowledge
that the DB may be inconsistent. At least with back-mdb. The safe thing
to do after such a crash is to throw away the DB and fetch the entire thing
from the provider. Which I gather would need to happen automatically
with such an option.
