  Adding a sysdep to detect that case is a good idea indeed!
  Rather than pretending it doesn't exist, though, I'd rather add a
different sysdep that tests its behaviour, so it can still be used
with the proper workaround.

  Testing the behaviour may be challenging, however, because I suspect
the CentOS 7 implementation of posix_spawn() is just racy, and they
simply documented that they don't care.
