Probably not. All modules modifying attributes and working with more
than one table need to be checked.

SQLite seems to behave different than the other db backends. The
SQLite locking mechanism is annoying, and the fact that the same
SQLite db should not be opened twice is equally annoying. Well, it's a
lite SQL db...
