+`net.Server.prototype._listen2` is an undocumented alias for an internal
+function that sets up the listening handle. It is kept only so that code
+replacing it keeps being called by [`server.listen()`][], and it will be
+removed in a future version of Node.js. Use [`server.listen()`][] instead of
+calling or overriding `_listen2`.
