- * The notification channel protocol is bidirectional and accommodates
- * synchronous and asynchronous communication modes:
- *
- *   - Synchronous: commands emitted by the client to which a reply is expected
- *     (e.g. subscribing/unsubscribing to conditions),
- *   - Asynchronous: notifications which are sent by the lttng_endpoint to the
- *     client as one of the subscribed condition has occurred.
- *
- * The nature of this hybrid communication mode means that asynchronous messages
- * (e.g. notifications) may be interleaved between synchronous messages (e.g. a
- * command and its reply).
- *
- * Notifications that are received between a command and its reply and enqueued
- * in the pending_notifications list.
