Yeah I'm afraid I don't understand what CLEANUP and tst_exit exactly
do. Hopefully Garrett can give an educated answer.

Right, the test is checking whether kill -1 inside a private pidns
kills all processes besides init in the pid namespace.

sshd is not in the private pid namespace and should not be killed.
If it is being killed by the pid -1 inside the container, then there
is a kernel bug.
