To add just a little bit, the side that closes the connection will get
a TIME_WAIT state.  Therefore, it's better for the side with fewer
connections to close the connection to reduce the chance of running
out of ports due to too many TIME_WAIT states. In most case, it's the
client side because the server side often handles much more connections.
