    Sorry for the late response (I've been away); "required" is perhaps
    putting it strongly, because as you say the information is there,
    somewhere. However, it would be nice to have, as standardized, that
    the third argument to the sa_sigaction handler be castable to a
    ucontext_t, as this would make porting signal-handling code between
    Linux flavours much easier.
