Process.spawn/poll/kill/free - non-blocking child processes with no shell: posix_spawn on macOS (process.ll), CreateProcessW with MSVC-quoted arguments and no console window on Windows (process_win.ll), linked only when a program uses Process.*. Http.save_to streams a response body into a file (NSURLSession with a run-time delegate class on macOS, the WinHTTP read loop on Windows); Http.received / Http.expected report progress while it is pending. Freeing a pending request cancels it and parks the slot until the worker has finished. App.window_hide / App.window_show take the game's window off the screen and back without closing it; the run goes on while hidden. Docs, examples, tests and a changeset.

Takes the game's window off the screen without closing it: its GL context or Vulkan surface, its size and its contents are kept, and the program goes on running — a hidden window does not end the run. App.window_show brings it back. It is how a launcher steps aside while the game it started with Process.spawn runs.
Keep the frame loop going while hidden so the child can be polled, but there is nothing to see: skip the drawing, and throttle the loop yourself — a hidden window is not paced by the display, so an unthrottled loop spins. It does not touch the boot splash (App.splash_hide does). Safe to call when there is no window yet, and twice. Headless there is no window and the call lowers to nothing.

orderOut: on macOS; ShowWindow(SW_HIDE) on Windows, which also forgets any key held as the window went.
