It is perfectly fine and expected to detach from the screen just by the UI disconnecting from nvim or exiting nvim. Just keep detach() in screen_basic_spec, to get some coverage of the detach method itself. This avoids hang on failure in many situations (though one could argue that detach() should be "fast", or at least "as fast as resize", which works in press-return already). Never use detach() just to change the size of the screen, try_resize() method exists for that specifically.
