Signals. Plain exit() isn't guaranteed to work in a signal handler. Come to think of it, though, RCS commands shouldn't be invoking _exit (or _Exit) in a signal handler: they should be killing themselves with the handled signal, so that their invokers get the proper status. Once this is done, RCS shouldn't need either _exit or _Exit.
