This looks like an implementation oversight rather than intentional
behaivor...
.. but it appears that only tcp_reass() checks SS_CANTRECVMORE before
putting an mbuf into a socket's receive queue (and not any of the
other paths, such as udp_input() or raw_input().
Anyone understand why this is the case? it seems clearly wrong to not
drop the recieved packet on the floor when the application has told
the kernel it's not interested in receiving further data from the
socket..
