Tim, are you actually considering attaching lots of databases at once ? This is a terrible idea. Every time you refer to an attached database SQLite has to find it. I don't know whether the list is hashed or not, but even hashed that means SQLite has to do a lot of work for every command. Plus reserve a lot of memory for the schemas for all these databases.
