Example: polling for events

This example shows that session/uid/seat/machine events can be waited for (using e.g. poll). This makes it easy to integrate Monitor in an external event loop:

>>> import select
>>> from systemd import login
>>> m = login.Monitor("machine")        # doctest: +SKIP
>>> p = select.poll()
>>> p.register(m, m.get_events())       # doctest: +SKIP
>>> login.machine_names()               # doctest: +SKIP
[]
>>> p.poll()                            # doctest: +SKIP
[(3, 1)]
>>> login.machine_names()               # doctest: +SKIP
