 * In node term the VS Code process calls `createServer`, then starts the server
 * process, waits until the server process has connected to the pipe / socket
 * and then signals that the connection has been established and messages can
 * be send back and forth. If the language server is implemented in a different
 * programm language the server simply needs to create a connection to the
 * passed pipe name or port number.
