My guess would be because it is still waiting for the remote end to
fully close the connection. This means there's the possibility of
further packets getting sent to that local ip:port. If you delete the
entry and the port gets reused you'll possibly have two remote ip:port's
both trying to send traffic to the same local ip:port and causing
erroneous RSTs of the connection.
Or something like that.
