IIRC, RMS said that using signal like that was very unclean and using throw
would be cleaner.

But I tend to agree with you that just using signal would be both
simpler and more correct (obeying inhibit-quit), and I really don't
see why using throw [making the implementation more trickly] can
be said to be (much) cleaner than your original approach!
