After this commit, tst-spawn and tst-spawn-static are failing for me,
with the following error messages:

tst-spawn.c:128: numeric comparison failure
   left: 29 (0x1d); from: errno
  right: 9 (0x9); from: EBADF
error: 1 test failures

tst-spawn.c:257: numeric comparison failure

  right: 0 (0x0); from: 0

And it's weird, because tst-spawn.c:128 is not a test for the newly
added fd5, it's an old test for fd1.

Have you seen similar results somewhere else?
