Right, but giving it more hints means it's more likely to do the smart
and fast thing.  For what it's worth, Taras is working on improving
the performance of SQLite in Firefox.  He has data that shows that
this can dramatically reduce the number of page faults (Taras, please
correct me if I'm misrepresenting things) when loading the database.
These leads to faster startup times of Firefox.
