> BDB JE copies any byte arrays and stores them in its cache.
> This means the message payload can exist in two places in memory.
> To avoid this, after persisting a P message, we can drop the payload, and lazily retrieve it from the cache at delivery.
> This technique may also provides a means to avoid paging..
