Then, if you are running it before main loop is setup, you can't call
gtk_main_quit(). I'd suggest you first run your subroutine, only after
it has finished setup callbacks which can invoke gtk_main_quit(), and
then run proper mainloop. And yes, setting things up so that quit can
happen cleanly even while in subroutine can be pretty painful, you may
need to play around with deferred function invocation and such to get
rid of warnings.

Cheers,
