+
+   Bind the socket to a free port and return the port number.  Relies on
+   ephemeral ports in order to ensure we are using an unbound port.  This is
+   important as many tests may be running simultaneously, especially in a
+   buildbot environment.  This method raises an exception if the
+   ``sock.family`` is :const:`~socket.AF_INET` and ``sock.type`` is
+   :const:`~socket.SOCK_STREAM`, and the socket has
+   :const:`~socket.SO_REUSEADDR` or :const:`~socket.SO_REUSEPORT` set on it.
+   Tests should never set these socket options for TCP/IP sockets.
+   The only case for setting these options is testing multicasting via
+   multiple UDP sockets.
+
+   Additionally, if the :const:`~socket.SO_EXCLUSIVEADDRUSE` socket option is
+   available (i.e. on Windows), it will be set on the socket.  This will
+   prevent anyone else from binding to our host/port for the duration of the
+   test.
+
+
+.. function:: find_unused_port(family=socket.AF_INET, socktype=socket.SOCK_STREAM)
+
+   Returns an unused port that should be suitable for binding.  This is
+   achieved by creating a temporary socket with the same family and type as
+   the ``sock`` parameter (default is :const:`~socket.AF_INET`,
+   :const:`~socket.SOCK_STREAM`),
+   and binding it to the specified host address (defaults to ``0.0.0.0``)
+   with the port set to 0, eliciting an unused ephemeral port from the OS.
+   The temporary socket is then closed and deleted, and the ephemeral port is
+   returned.
+
+   Either this method or :func:`bind_port` should be used for any tests
+   where a server socket needs to be bound to a particular port for the
+   duration of the test.
+   Which one to use depends on whether the calling code is creating a python
+   socket, or if an unused port needs to be provided in a constructor
+   or passed to an external program (i.e. the ``-accept`` argument to
+   openssl's s_server mode).  Always prefer :func:`bind_port` over
+   :func:`find_unused_port` where possible.  Using a hard coded port is
+   discouraged since it can makes multiple instances of the test impossible to
+   run simultaneously, which is a problem for buildbots.
