Tried this at the top of db.py and at the top of my controller to no avail. (I replaced the 'from gluon.custom_import import track_changes; track_changes()' with your code).
I guess the persistence of the instantiation is because the interpreter is started once when starting web2py webserver (maybe this does not occur when using apache2 or lighttpd?).
