Just to confirm, that was the source of my question... I've got two

wasn't a way to do it, but I thought I'd ask anyway.
How is it possible that one or both of your processes do not have rwx
permissions on the /tmp directory? Did you do something with
chroot(8) that you're not telling us? If so, then Don't Do That.
Make sure the processes a have a common path to an AF_UNIX socket
where you can pass file descriptors between them.
