The podman approach seemed to work, and I was able to run all three
steps. Didn't see any hangs. I'm going to try again dropping down
the innodb pool size (box only has 32G of RAM).

The storage can do a lot more than 5k IOPS, I'm going to try ramping
that up.

Does your reproducer box have multiple NUMA nodes, or is it a single
socket/nod box?
