/**
+ *
+ * Publishing and Managing State
+ * ======
+ *
+ * After applying changes, the Editor queues a worker to publish mail, feed,
+ * and notifications, and to perform other background work like updating search
+ * indexes. This allows it to do this work without impacting performance for
+ * users.
+ *
+ * When work is moved to the daemons, the Editor state is serialized by
+ * @{method:getWorkerState}, then reloaded in a daemon process by
+ * @{method:loadWorkerState}. **This is fragile.**
+ *
+ * State is not persisted into the daemons by default, because we can not send
+ * arbitrary objects into the queue. This means the default behavior of any
+ * state properties is to reset to their defaults without warning prior to
+ * publishing.
+ *
+ * The easiest way to avoid this is to keep Editors stateless: the overwhelming
+ * majority of Editors can be written statelessly. If you need to maintain
+ * state, you can either:
+ *
+ * - not require state to exist during publishing; or
+ * - pass state to the daemons by implementing @{method:getCustomWorkerState}
+ * and @{method:loadCustomWorkerState}.
+ *
+ * This architecture isn't ideal, and we may eventually split this class into
+ * "Editor" and "Publisher" parts to make it more robust. See T6367 for some
+ * discussion and context.
