Check my previous post in the thread. My argument was that even if you 
implement a LIFO to store the messages, the rest of the network behaves 
in FIFO way (that's the nature of networking). Thus what you'll get 
would be some kind of LIFO/FIFO mixture with no clear semantics.

On the other hand, priority queues maintain the FIFO semantics so there 
should be no crucial problem with implementing it.
