Sorry I haven't read that. Will do.

Pl see the question I posed to in response to Ted's email. Having an
implicit ABORT or having a socket option is very useful thing. It is the
"basic infrastructure" needed in TCP and TCP API layer (like sockets).
Now, if I follow RFC 1122 language, it seems to preclude me from doing
the above. Doing such a thing is an RFC voliation? Does it need some
clarification?

IMO, one problem we are trying to address ( the main issue) is the RFC
language correction/clarification.

Question : OTOH, I think you are asking for clear "problem statement" ?
Are you saying that the the way it is stated in the document is vague,
does it more clarification? I can read it again and again, but if you
can ask some specfic questions, maybe that would help. Other responses
have been of the nature which I summarised earlier and I don't remember
anyone having issues about the problem statement.
