Forgot to answer this one: this is only with a few parallel logins,
but many logins over a period of hours.

Which raises the question: what is systemd-logind going to do when
more than 1024 users log in to a machine at the same time?

Which raises the more general question: what will other services like
systemd-stdout-syslog-bridge do when the number of processes that log
go into the hundreds? I haven't thought about it carefully, but there
seems to be some cases where one could run into the default limit of
1024 open files.
