I suspect what's happening is that the library on your build hosts
defined O_CLOEXEC, but your kernel lacks support for it.   fcntl(fd,
F_GETFL) may just return the original flags we passed, meaning that
it's not a guarantee that the O_CLOEXEC actually had an effect.

Please test the attached alternative patch and let me know if it
solves your problem.
