Well, I responded to the group that I had taken one of the fellows advice
posting here, and modified the tcp_usrclosed in netinet/tcp_usrreq.c.
So all is well -- it gets TCPS_CLOSED state and the tcps_close() function
called on the tuple IMMEDIATELY. It doesn't switch states depending on
which state the connection is currently in. I also made a sysctl variable
for it (to turn the "feature" on or off), and will post the small patch
along w/ some other small changes I have made soon.
Thanks,
Brandon
