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.

Releases the handle so it can be reused. It does <strong>not</strong> stop a child that is still running — use <a href="process-kill.html"><code>Process.kill</code></a> first for that; such a child keeps running and is reaped by the runtime when it ends, so it never lingers as a zombie. After <code>free</code>, polling the old handle answers <code>255</code>.
