void spawnAsync(string workingDirectory,  string[]  argv,  string[]  envv,  glib.types.SpawnFlags spawnFlags,  glib.types.SpawnChildSetupFunc childSetup,  int  timeout,  gio.cancellable.Cancellable cancellable =  null,  gio.types.AsyncReadyCallback callback =  null)

Like [vte.pty.Pty.spawnWithFdsAsync], except that this function does not allow passing file descriptors to the child process. See [vte.pty.Pty.spawnWithFdsAsync] for more information.
