Signature downloading and DB validation was being based on the most recent download status for the DB. If a DB successfully downloaded but a signature did not, db_update would move to the next server. If the next server tried does not have a more recent copy of the DB, db_update would not download the DB again and would forget that the DB had previously been updated. In this case it would skip validation entirely, leaving an updated DB with the original validation status.
