This affects async commands started by client API, commands with async capability run in a sync way by client API (think mpv_command_node() with "subprocess"), and detached async work. Since scripts might want to do some cleanup work (that might involve launching processes, don't ask), we don't unconditionally kill everything on exit, but apply an arbitrary timeout of 2 seconds until async commands are aborted.
