Require resizeterm This allows us to get rid of the endwin, which causes problems. Specifically that ncurses will query the size itself on the next doupdate, causing a potential race. It also results in an annoying flicker that we see in typwindelta. If we punt passing arguments to owl_global_resize, I think we can support resizeterm-less curses with a bit of a dance: endwin() h,w = query_terminal_size() relayout_windows(h, w) doupdate() if (h,w != query_ncurses_size()) h,w = query_ncurses_size() relayout_windows(h, w) (This will only flicker given a race.) That said, this is annoying and we build with our own curses on athena 9. We may as well just assume it's there.
