Yes, but many programs keep a connection to the database the whole time they're run, but seldom do anything with it. If someone was using the default journal_mode (= DELETE) then there might be no journal file even though there was a connection.

True only if you have done "locking_mode = EXCLUSIVE" and have already started a transaction. Maybe there needs to be a little table which shows how these two PRAGMAs interact. Simon.
