At a guess, this is a difference in what is being reported, right?

I'm guessing that pan is now reporting number of "parts", not
number of article headers downloaded.  Good guess, or bad?

This is still true, and pan-0.127 crashed five times in my attempts to
work my way through the process of figuring out where it's fragile.

Do not, under any circumstances, try to delete the contents of a group
while the header download is in progress.  Badness ensues.
