E.g., we need this information to make RabbitMQ AMQP broker cluster to forget this node until it goes up again. This is easily achievable if we stop the instance on the node - then notification is sent to clone instances and everything is fine. But what can we do if node goes offline unexpectedly? Is there any way to notify other clones that the slave is dead and perform corresponding actions?

Didn't we generate notifications for nodes that were fenced, just as if
the instances on them were stopped?
