Because absent other information, it is impossible for TCP to tell the
difference between a simplex connection (send only relative to the
CLOSE_WAIT end) and an incomplete connection tear-down.

Anything in the stack that arbitrarily nuked such a connection from
the CLOSE_WAIT end is at best guessing.

Even TCP Keepalives cannot really deal with this since it is likely
there is still a TCP endpoint in FIN_WAIT_2 at the other end.

This will be an excellent test of the third party's responsiveness to
bugreports.
