title: Commit existing journal file in SQLite from prior terminated connection to database
body: <p>I'm prototyping a script that creates large SQLite databases with a four day time limit.  The time limit was reached before the script finished and the connection.commit() command would be executed.  The script is dropped and the database connection terminated but the journal is still in the file directory where the database was being created.</p>
  
  <p>I'd like to commit the existing journal to see if the current script is on the right track.  Initially I just try (using the Python sqlite3 module on iPython):</p>
  
  <pre><code>connection = sqlite3.connect('mydatabase')
  
  connection.commit()
  </code></pre>
  
  <p>but I suspect I need to specify that I want to commit the existing journal.  I tried passing the journal name as an argument in commit(), but commit() doesn't take arguments in the sqlite3 Python module.</p>
  
  <p>In the future I'll incrementally .commit()</p>
