I believe the install scripts in the RPM stop and restart Mailman. But I will
do an explicit shutdown of Mailman before the upgrade when I try it again.

That page relates to upgrading from 2.1.5-20 or earlier. I was upgrading from
2.1.9, so that does not apply (?). When I did an upgrade to 2.1.16 from an
'bare' install of 2.1.9 on my home system, there weren't any (major) problems.
And a fresh install of 2.1.16 (on another machine) had no problems either.
Ok, I did an explict stop of mailman, removed the old rpm (rpm -e) and then a
fresh install of the new version, started mailman, and after some minor config
tweaks, it seems to be working.
