  [;1m-spec spawn_link(Fun) -> pid() when Fun :: function().[0m

  Returns the process identifier of a new process started by the
  application of [;;4mFun[0m to the empty list [;;4m[][0m. A link is created
  between the calling process and the new process, atomically.
  Otherwise works like [;;4mspawn/3[0m.
