@Vincent: I have confirmed for sure that this new code is still halting at
1024 open files.

system-local.conf is set to:

<!DOCTYPE busconfig PUBLIC
"-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN"
"http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd";>
<busconfig>
<limit name="max_connections_per_user">5000</limit>
<limit name="max_completed_connections">2000000</limit>
<limit name="max_incomplete_connections">60000</limit>
<limit name="max_replies_per_connection">100000</limit>
<limit name="max_pending_service_starts">30000</limit>
<limit name="max_match_rules_per_connection">100000</limit>
<limit name="max_incoming_bytes">2000000000</limit>
<limit name="max_incoming_unix_fds">500000000</limit>
</busconfig>

I know for sure this file is being read and used because prior to this issue, I
had to do some tuning to get past 80 users. As soon as the dbus process hits
1024 it stops working and no additional users can log into the server.
