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.

# process.ludic — Process.* : start a child, poll it without waiting, read its exit code.
