gtk_main_quit() doesn't exit the program, it simply returns from the
inner-most gtk_main_iteration(), typically called by gtk_run().
therefore, all cleanup can go right after you return from gtk_run(). 

gtk_main_quit() is quite problematic if you ever use recursive
invocations of gtk_run()/gtk_main_iteration(). not impossible to use,
but it took me a long time to figure out a reliable way to exit a
program that was potentially nested within 2 or even 3 levels of
gtk_main_iteration().

ps. the solution was to add gtk_main_quit() as an idle callback
