It looks like mpirun executes podman with extra open file descriptor(s) but they
are not available to the container.
In this Podman GitHub discussion thread
https://github.com/containers/podman/discussions/13254
it was discussed if the option
--preserve-fds
could be used to pass in extra file descriptors from mpirun to the container.
A showstopper was that the file descriptor(s) passed in
were not continuous (sequential).
