Re: select_for_update().get(...), what happens on DoesNotExist?

The question is going to be very database specific. "select for update" works by putting in row-level locks in the database. If the row does not exist, then it won't get a lock on it, and I know of no databases that will maintain the query so that any newly created rows automatically get a lock
