I really don't like this idea because it is so much of a kludge. I
suppose, though, thinking more about it, that since the effect will be
to change a 5xx error into a 4xx error, it might be a tolerable kludge.
A possible problem is that not all Unix-like OS have the same set of
error values, though that can be coped with by the use of #ifdefs, I
suppose.
