> {{ClusterExpirationManager.checkExpiredMaxIdle()}} sends a {{TouchCommand}} to the other owners and expires the entry locally if the touch was unsuccessful.
> {{ScatteredTouchResponseCollector}} is stateless, and reports that the entry has not been touched if it doesn't receive any {{true}} response. However, this is only correct if at least one backup entry existing on another node, and that is not the always the case: e.g. between the backup node leaving the cluster and another node becoming a backup, or when the cluster has a single node.
> Since {{ClusterExpirationManager.checkExpiredMaxIdle()}} is called on every read, before the entry being expired on the local node, it means a transient entry in a scattered cache with a single node will expire on the first read, immediately after being inserted.
