def __repr__(self):
            """Based on original __repr__ from CPython 3.4's mp package.

            Reasons for re-implementing:

            * The original code would invoke os.waitpid() through
              _popen.poll(). This is forbidden in the context of gipc.
              This method instead reads the exitcode property which is set
              asynchronously by a libev child watcher callback.

            * The original code distinguishes 'initial' state from 'started'
              state. This is not necessary, as gipc starts processes right
              away.

            * This method removes the `if self is _current_process` check
              without changing output behavior (that's still 'started' status).
