I rewrote netcat's readwrite() to use select() instead of the poll()
systemcall but read() on the network file descriptor still does not 
return EOF.  So netcat is not notified that the SCTP association has 
been closed.

Starting SCTP server:
$ nc -c -l 55555

Starting SCTP client:
$ nc -c 55555

Now send a SIGINT (ctl-c) to client or server.  Sending SIGINT using 
TCP sockets will terminate the connection immediately and notifing
the other side.
