Not with leafnode-1 either.

Hm. There is no difference at all in the log files for the
select_group action:
$ diff slrn_leafnode-2.log slrn_leafnode-1.log

The only difference /in the log/ is that in the meantime 2 more
message have arrived. Still, with leafnode-2, it took slrn
several seconds to enter a group with 35 unread messages, whereas
with leafnode-1 I can enter instantly.
Even more confusing is the fact that both servers behave the same
way, if I select *all* messages in a group.
