Kevin,
This one is for you:
Two sessions, in transaction:
Process A Process B
update session where id = X;
update order where orderid = 5;
update order where orderid = 5;
update order where orderid = 5;
... deadlock error.
It seems like we ought to be able to avoid a deadlock in this case;
there's a clear precedence of who grabbed the order row first. Does
your serializability patch address the above situation at all?
