  | The *real* WTF there is that the code doesn't actually know if fd 3 is
  | known to be open on a file that should, or if it's just a stray leaked fd.

I don't know why fd 3 was wanted to be a dup of stdin, but aside from
that oddity, there's notthing remarkable about the code (no WTF), the
test is just avoiding a (pointless) dup2(3,3).

Whatever fd 3 was before executing this code, it is closed after it
unless it happened to be what is wanted on stdin.
