I think we should drop the up-latch. I don't see how messages can get 
received before a view (after the STOP-FLUSH message has been applied 
(and ack'ed)). I also don't see how receiving a message before unblock 
(but after VIEW) would break virtual synchrony...

Do you want to discuss this offline ?
