No. It might be usual ssh behaviour, but it's wrong behaviour and is
related to the zombie issue. Please re-read my earlier posts to the
thread.

You won't see zombies if process 14925 reads exit status of process 14926
before it exits.
Yes, runit should reap that status, but that doesn't change the fact that
ssh is wrong. Note also that SIGCHLD is delivered to sshd process, not to
runit, because 14926 terminates before 14925.
IMO this is a bug in the privilege separation code in openssh.
