Jonathan Lemon 272c5dfe93 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.

Test case supplied by: Tim Robbins <tjr@FreeBSD.ORG>
