If you do this that would mean that you could have no shared locks safely on the SQLite database while you have a reserved lock, that is, if one process is planning to write to the database, other processes cannot even read it. Even then, you would have to be very very careful if you want to avoid losing data. Basically, unless you can (and willing to) write your own SQLite VFS that is designed to handle this safely, I wouldn't do it.
