See tcp_usrclosed() in /usr/src/sys/netinet/tcp_usrreq.c. Replace that code
with something like (untested):
tp->t_state = TCPS_CLOSED;
tp = tcp_close(tp);
return tp;
...and you'll break your TCP/IP stack in the fashion you've asked for.
If other things break too, you can keep all of the pieces. :-)
