                          Default          Recommended?
  --with-duplicate-db=DB  db3_nosync       skiplist
  --with-mboxlist-db=DB   db3              skiplist
  --with-seen-db=DB       flat             skiplist 
  --with-subs-db=DB       flat
  --with-tls-db=DB        db3_nosync

Going through past emails, it seems now that skiplist is recommended
essentially for everything. Is that plausible? Comments?
