This would be nice.  However, I am experiencing 'db lockers' issue with
berkeley db.  'db lockers' keep growing until deliver.db and
tls_sessions.db become unaccessable to cyrus (DBERROR: opening
/export/cyrus/deliver.db: Not enough space).  There is still plenty of
disk space available.  At this point duplicate suppression stops working.
I hate to add quota to berkeley db facility at this point.  I am using
cyrus 2.2 (fairly recent CVS version, berkeley db 4.1.25p1 and solaris 9).

I've seen others have similar problems, but mostly with mailboxes db.  I
am not sure if this is cyrus or berkeley issue at this point.  I am still
researching sleepycat api docs.  Is anyone using skiplist for deliver.db
with success?
