class_docstr: :class:`Pod` is a thread/process- container of :class:`BaseRuntime`. It leverages :class:`multiprocessing.Process` to manage the lifecycle of a :class:`BaseRuntime` object in a robust way.
  
  A :class:`Pod` must be equipped with a proper :class:`Runtime` class to work.
docstr: Start the Pod.
  This method calls :meth:`start` in :class:`multiprocesssing.Process`.
