The raw bsddb interface wants keys and values to be strings and for
btree access methods, the length doesn't really matter. You could
pickle the 2-tuples or just do something easily splittable like '%s|%s'
Sounds like one BTree table would do the trick there.

Each of those would be a separate table, of course. bag_of_token maps
sounds like you'd want to pickle the data value.
