-/* In this test, we have two senders sending one message to a common receiver.
- * The receiver should be able to see any ordering between the two messages.
- * If we model-check the application with assertions on a specific order of
- * the messages (see the assertions in the receiver code), it should fail
- * because both ordering are possible.
- *
- * If the senders sends the message directly, the current version of the MC
- * finds that the ordering may differ and the MC find a counter-example.
- *
- * However, if the senders send the message in a mutex, the MC always let
- * the first process take the mutex because it thinks that the effect of
- * a mutex is purely local: the ordering of the messages is always the same
- * and the MC does not find the counter-example.
