#### Well, I want to destroy these widgets, but if I do that, they get referenced again, and eventually I get a SEGV. So instead of destroying them, I’ll just hide them, and leak a bunch of memory every time the disk file changes. Go go go Gtk!

Michael! What are you doing? You’re messing this all up!
Who the f*ck are you?
Your conscience! You can do better! I can do this way

Shhiiiiit, who cares? It’s too goddamn late you bastard. You
should have come up with that earlier. This game is down on
its knees already. Dying from hacks spreading like cancer…
