I see, the pane_string in tty_menu_show, for example.

The char * in the tty_menu would keep the string_data alive and
immovable if they were on the stack somewhere. Alas, I don't understand
how the menus are handled. Is there some form of "event loop" running
when the menu is up and interacted with? Or is it "normal" keyboard.c
input handling?
