Tells, after tcp_bind/2, the socket to listen for incoming
requests for connections. Backlog indicates how many pending
connection requests are allowed. Pending requests are requests
that are not yet acknowledged using tcp_accept/3. If the
indicated number is exceeded, the requesting client will be
signalled that the service is currently not available. A
commonly used default value for Backlog is 5.
