Yep, in the next sentence Derek mentioned "dispense with shutdown",
meaning the shutdown(2) syscall that does exactly that. What he meant
was, wouldn't it be nice to be able to do that with close(2) instead?
G'luck,

Now what would have been useful is a way to have
distinct fd's for the
local read and write end of (e.g.) a TCP socket - such that one
direction could be closed w/o closing the other.
I believe that this can be done, now. At least I've read that it's possible
for one end to close (FIN) a TCP connection without the other end also
closing. Thus you end up with the one-way data flow that is still ACKed the
way that TCP does.
