The situation is simple: we have events (objects) that have to be 
indexed by date. We currently use an OOBTree with the days as keys and 
lists of objects as values. The objective is to avoid rewriting these 
lists each time something changes, since we can have tens of thousands 
of events in the same day. Some kind of btree-based list or set would 
work, I guess.

Well, it's an index of dates, so, I guess we could use integers as keys 
instead of strings, as we are now.
