OK.  I've added text to the bottom of Section 4 "Global Requests" as
follows:

   In general, the reply messages do not include request type
   identifiers.  To make it possible for the originator of a request to
   identify to which request each reply refers, it is REQUIRED that
   replies to SSH_MSG_GLOBAL_REQUESTS MUST be sent in the same order as
   the corresponding request messages.  For channel requests, replies
   that relate to the same channel MUST also be replied to in the right
   order.  However, channel requests for distinct channels MAY be
   replied to out-of-order.


Is this acceptable?

Thanks,
Chris
