Good point. For system sleep, the pm app knows best how to prepare this
tricky thing. So Suspend()/Hibernate() is generally located there. For
shutdown, and thus saving the session, saving all unsaved documents,
etc. the desktop base itself should know best. So the method should got
there. It might be clever to let Suspend()/Hibernate() be implemented by
the pm app and Shutdown()/Reboot() by the desktop base. That wouldn't be
possible with this spec IMO.
