I don't have a separate thread that does the DB scanning.
The sequence of operations is something like this:

1 * Init various GUI elements including the track treeview.
2 * Read the DB and append elements to the treeview.
3 * call gtk_main() and wait for events.

Now, if the user quits between 2 and 3, it becomes an issue because gtk_main()
hasn't been called yet and I can't check for the main loop.
If gtk_main() has been invoked, I can check for the existence of the mainloop like this:

while(gtk_events_pending())
        if (gtk_main_iteration_do(FALSE))
                return;

Is spawning a thread and cooking up some simple synchronization scheme the only
way to quit gracefully ?
