Sorry about my late reply, I've been busy with exams and work, and haven't
had any time for my hobby programming attempts. Anyway, I'm sorry, but I
should've mentioned that I've tried that too, unsuccessfully.

Here's a more recent attempt of mine, just to test:

public static void ShowSplash(object sender, EventArgs e)
	MainWindow window = new MainWindow();
	Console.WriteLine("Before Sleep");
	Console.WriteLine("After Sleep");

public static void Main (string[] args)
	Console.WriteLine("Before Run");

Now, the console shows, in order, "Before Run", "Before Sleep", "After
Sleep". The MainWindow, despite being run in a Gtk.Application invocation,
does not show until after the function returns. In other words, attempting
to show a splash screen and doing some heavy work there would result in the
same problem as the one I'm having. Thanks for your reply, but it is
unfortunately no solution.

I can't believe this can be so hard to do. Is this really that uncommon a
scenario? You'd think there'd be something about doing something like this
in the documentation or some website or blog, but I fail to find any
information anywhere on this topic...
