When a page in an SQLite database file is modified, the old page data is written to the journal file. Later on, if a rollback is required, the original data is copied out of the journal file back into the database. If the INSERT statements are causing the database to grow, then the new pages appended to the end of the file do not have to be journalled, as there is no "old data". If a rollback is required, SQLite will just truncate the database file back to its original size. So the journal file does not grow.
