I want to try to bring some focus back on the above point that the draft 
is trying to make.

If we agree that there is a problem and the solution lies in aborting 
the connection, however it is done, i.e. by application or by some TCP 
implementation, then at the minimum we believe that a change is required 
in the verbiage of RFC 1122. The change is to say that in case of 
reliable ACK's coming back from the receiver, it is NOT a requirement 
for the sender to keep the connection open indefinitely.

Can we agree on this?
