Public bug reported:

When running several containers at the same time on our GitLab runner,
Podman sometimes crashes with "fatal error: concurrent map writes" in
"github.com/containers/podman/pkg/api/handlers/compat/networks.go:153".
This has been reported upstream in
https://github.com/containers/podman/issues/22330 and was fixed in
https://github.com/containers/podman/pull/22332. The fix was also
backported to the 4.9 branch
(https://github.com/containers/podman/pull/22835), where it applied
cleanly, and then shipped as part of Podman 4.9.5
(https://github.com/containers/podman/releases/tag/v4.9.5).

It would be great if this fix could be added to the Ubuntu 24.04 package
for Podman as well to fix these crashes.
