I'm of the opinion that you should never use mmap, because if you get an I/O error of some kind, the OS raises a signal, which SQLite is unable to catch, and so the process dies. When you are not using mmap, SQLite gets back an error code from an I/O error and is able to take remedial action, or at least compose an error message.
