> 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.
