you can make a new Session() with expire_on_commit=False, that can be from your sessionmaker. the settings you apply there override whats in the original factory.
Though for status logging I tend to just use a separate Session/transaction for that, that way the main transaction can maintain atomicity while the "status" value is visible from the outside.
