/**
*
* 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.
*
* @task mail Sending Mail
* @task feed Publishing Feed Stories
* @task search Search Index
* @task files Integration with Files
* @task workers Managing Workers
