	LAST_ACK means both sides of the connection have sent FINs
to each other.  The side in LAST_ACK is waiting for the FIN it sent
to be ack'ed.

	The only way I can think to kill it off is to somehow forge
a TCP packet with the reset bit set and send it to the connection
stuck in FIN_WAIT from another host.  You could build a command
that would take the necessary ip addresses and tcp ports as arguements
to do it if you had raw access to the network.  It could be done, but
it would be a pain to write.

	If that were the case, you would be in ESTABLISHED, FIN_WAIT_1
or FIN_WAIT_2, not LAST_ACK.
