Example: polling for journal events
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This example shows that journal events can be waited for (using
e.g. `poll`). This makes it easy to integrate Reader in an external
event loop:

  >>> import select
  >>> from systemd import journal
  >>> j = journal.Reader()
  >>> j.seek_tail()
  >>> p = select.poll()
  >>> p.register(j, select.POLLIN)
  >>> p.poll()
  [(3, 1)]
  >>> j.get_next()
