Hmm, maybe a selinux policy or something like that is preventing some
system call from working, and this causes a Perl call to fail which we
may be failing to report; for instance we have
        open(ORIG_STDOUT, ">&STDOUT");
in's INIT block, without an "or die" which would let us know
that it failed.
