I'll give that a try, but I'm wanting to go back to the middle, where
I had hit tab to read a selected thread, rather than to the beginning.
Matt Ackeret suggested this might be a feature rather than a bug,
in which case trn may still have a valid index to the previous page in
the thread selector.  If so, there may be a command to make use of that.
Until now I've been remembering the percentage displayed at the bottom
of the thread selector and using "<" to move back to that vicinity.
All things considered, this certainly is a minor nuisance compared to
memory leaks, crashes and non-ascii character support.

Since I don't read any binary groups, that probably is the difference.
But, some text groups that I do read have 500-1000 articles per day, and
I sometimes go several days to a week before accessing their overviews.
But I don't think I have ever reached 50k of actual new articles (as
opposed to article numbers).  I don't run the server, so I'm not up on
the retention periods, but 100k spooled articles may be an upper bound
for the text groups that I'm reading/skimming.

I haven't looked at the relevant statistics, but I suspect that Usenet
traffic hasn't increased all that much since the turn of the millennia,
certainly not compared to other Internet traffic.  OTOH, the binary
groups may differ significantly.  Still, increased traffic (or greater
retention--bigger disks!) might be enough to hit one threshold or another.
