The socketpair(0 syscall is bogusly returning the fd numbers through
the primary and secondary return codes, causing it to not behave as
documented. This probably originates from the ancient BSD kernels that
had pipe(2) implemented by socketpair(2), there are no binaries left that
we can run that do this.
