Hm... there is no duplicate_db in /var/lib/cyrus/ ...?

There is a deliver.db, and some google matches earlier today seemed to
indicate that from v2 on of cyrus, the deliver and duplicate databases
have been joined.

What happens if I remove deliver.db?  Is it harmless?  Will I trash my
cyrus installation for all future?

deliver.db is dated Aug 1, and that's about when my problems started.
