if you shutdown your pc and have apps open the apps don't "stop" the shutdown and ask to save

This thread does bring up a good question:  what kind of notification do
applications get that the system is being shut down (or the user is
logging off, it's all the same to the app)?  As an example: In Windows,
applications get a signal that they are being shutdown and they can
respond to it.  This is where Word would ask you to save your file, etc.
The downside is that applications can prevent the logoff/shutdown from
happening and that can cause maddening system 'hangs'.  Is there such a
signal that Linux/UNIX apps receive?  Does it come from X, Gnome/KDE?
