  The tcp_connect() function returns immediately; it does not wait for
  the connection to be properly setup. Instead, it will call the
  function specified as the fourth argument (the "connected" argument)
  when the connection is established. If the connection could not be
  properly established, either because the other host refused the
  connection or because the other host didn't answer, the "err"
  callback function of this pcb (registered with tcp_err, see below)
  will be called.
