There is usually a graceful way for some apps. You will have to
individually treat each app, check whether it is running, and if it is
running then use commands adapted to that particular app.
For example all gvim instances run as servers (vim probably doesn't by
default) and you can send remote commands to them and make them save and
quit. Similarly, many apps have dbus instances and often if you browse
through the dbus tree, you will find that it has a quit command.
