Transaction A locks 1 and wants a lock on 2
Transaction B locks 2 and wants a lock on 3
Transaction C locks 3 and wants a lock on 1
I've never had the deadlock detector successfully deal with the above.
Let alone a 4-way.

Deadlock termination kills *all* of the transactions involved in the
deadlock; what else could it do? This is as opposed to serialization
failures, in which usually only one of the transactions involved fails.
