Nope, it's executing both times, it just doesn't do what you think it
does.

$widget->set_size_request (x,y) says to gtk+:

 Please would you make my widget at least x pixels wide and y pixels high?

If widget is already x (or more) pixels wide and/or y (or more) pixels
high, gtk+ thinks to itself, "Oh. The program already has enough space. I
don't need to do anything." :)

There is no $widget->set_maximum_size (x,y) in gtk+.

If you want to remake a window so that it's as small as possible, this is
how I do it.

Remove the top-level widget from it first. (i.e. its HBox or VBox)
$window->show_all;
$window->set_size_request (0,0);
Re-add the top-level box back.
$window->show_all;
