This was re-discussed on the Wed. call, with the following results:
1. Message transport layer takes care of ack retransmission in case of a  
packet loss.
2. Confirm/Fail message responses should be sent out without waiting on the  
receipt of the message ack.
[comment on error recovery: if message transport layer is broken, say  
unidirectionally, the ack sending will eventually timeout and generate a  
message transport error that the NSA will need to handle]
3. From the receiving state machine perspective, receiving a confirm/fail  
message from a particular NSA should cancel out the need to receive an ACK.  
So the state machine should not only continue to process the confirm/fail  
message, but not gate on or wait for the ACK message.

Hope this resolves this issue
