cleanUp(owner: ActorRef, deadLetters: MessageQueue): Unit
Called when the mailbox this queue belongs to is disposed of.
Called when the mailbox this queue belongs to is disposed of. Normally it is expected to transfer all remaining messages into the dead letter queue which is passed in. The owner of this MessageQueue is passed in if available (e.g. for creating DeadLetters()), “/deadletters” otherwise.

count(): Int
This method returns an upper bound on the queue size at the time it starts executing.
This method returns an upper bound on the queue size at the time it starts executing. It may spuriously return smaller values (including zero) if the consumer pulls items out concurrently.
This method can be used from any thread.
- returns
an upper bound on queue length at some time in the past
