"Timed wait" is the final stage when a TCP connection is closed.  TCP has
the notion of "maximum segment lifetime" - how long a datagram might
remain somewhere in the network.  Before a connection is completely
closed, it remains in the "timed wait" state for twice this maximum
segment lifetime.  The purpose is to allow any left-over or duplicate
datagrams related to this connection to be delivered, so that they cannot
be confused with data from new connections.

If you repeat the netstat command enough time later, you should not see
any remnant of the connection in the "timed wait" state.
