Yes, that would be the expected effect of putting in a session_commit() at the

Yes, that would be a way to go. Another alternative is to re-start the session 
each time you want to write an updated value into it and then immediately close 
it again. The cost of opening and closing a session to write a value into it 
compared to opening and closing a file to write a value into it may be a factor 
here, but I leave that comparison as an exercise for the reader.

Others on the list may, of course, chip in with further options, or have other 
useful, or at least witty, comments.
