Hi Hendrik, Thanks for reaching out!

I created a test image that takes several minutes to stop when the container got signaled to stop. So when I call podman stop with a long timeout the call hangs a few minutes until the container stops. When I use a second terminal while the podman stop call is wating for the container to stop some podman calls hang as well. For example a podman inspect on the same container or a simple podman ps hangs. If I use ctrl-c to kill the earlier podman stop call then those hanging commands continue straight away. Are things supposed to behave that way? Yes, that's expected behaviour. The container is locked while it's being stopped.  The lock blocks other commands from using the container. I am optimistic that we can improve the locking and introduce an intermediate state between "running" and "stopped" and unlock the container.  I am pulling Matt Heon who likely has the best understanding how we can achieve it. Matt, what do you think?
