I agree in general, but I'm not sure this one is not a burning issue.
I don't think the fact it never surfaced before is significant (see my
other mail).  But I won't argue with you about the order in which you
are attacking problems.

What _are_ the burning issues that are left unsolved, btw?

How can we detect that a particular handle is a pipe?  Handle zero is
not special: some program could close it and open some file on it.
