> PagedMessage may be GCed before it was acknowledged. In this case, server has
> to reload the page and hold the page cache lock, then block other consumers
> of the same queue.
> When do acknowledge, we need at least message id, transaction id, and is
> large message.
> We believe the three property can be added to PagedReference, so we do not
> rely on PagedMessage when acknowledge except LargeMessage.
