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.

Starts the program at path with the arguments in args (a []string; the child's argv[0] is path) and returns a handle >= 0 straight away, or -1 when the program could not be started — a missing file, a file that is not executable, or all 16 handles in use.
No shell is involved, so every argument reaches the child exactly as written: spaces, quotes and $ are not interpreted. The child inherits this process's environment and working directory. On Windows the arguments are joined into one command line quoted so the child's C runtime splits it back into the same list, the path and arguments cross as UTF-8 and are converted to UTF-16, and the child is started without a console window (a GUI program is unaffected; a console program runs hidden). Use an absolute path: there is no PATH search.

See Process.poll for the exit code.
