>
>While this won't prevent the deadlock, it should catch the case where
>a deadlock causes the DB update to fail and provide feedback to the user
>and rollback the transaction
>
>I don't know how to trigger the deadlock, I can only confirm that we see it, and
>that this should catch it.
>
>To test:
>1 - Apply patches
>2 - Checkout several items to a patron
>3 - Confirm that 'Renew all' feature continues to work as expected and all items are renewed
