I just realized that RFC793 says to go from CLOSE-WAIT to LAST-ACK state
on page 23, and this would appear to be the Right Thing (no need to enter
CLOSING and thus TIME-WAIT since the other end's FIN is acked by this end's
FIN).  However, on page 61 it says to enter CLOSING state.

Which page is in error?

(Please no flames for having implemented my TCP directly out of RFC793 and
never looking at how UNIX does it or anything -- I've heard it before.)
