TCP_NODELAY effect how the socket reacts when you send data on it. Not
how it reacts when you close it.
Look at setsockopt(.... SO_LINGER). and in C make sure you shutdown()
the socket before you call close. (read the shutdown man page).
If you just call close() on a socket, you can certainly loose data
you've written to it that has yet to be transmitted.
