That's the one.  To summarize my later findings for posterity, this
isn't a "bug" in libpam-modules per se but a known bad-interaction
between systemd and gnome.

In short, systemd implements its own system for setting process limits
on login, and /etc/security/limits.* are obsolete.

Here's the Link I Needed To Find:

https://bugzilla.redhat.com/show_bug.cgi?id=1364332

The bummer is that systemd's mechanism for setting limits is less
powerful than the limits.conf style and doesn't permit setting limits
for users based on group membership.

I still haven't nailed the workaround (the ideas in the fedora thread
above haven't worked, but I have little understanding of how systemd
manages processes so I'm sort of poking in the dark) but I will post a
followup to this thread when I do so that others might benefit as well.
