  Modified files:
    sys/netinet          tcp_input.c 
  Log:
  In timewait state, if the incoming segment is a pure in-sequence ack
  that matches snd_max, then do not respond with an ack, just drop the
  segment.  This fixes a problem where a simultaneous close results in
  an ack loop between two time-wait states.
