Ok, I said

break dispnew.c:4816
run -nw

and then

commands
continue
end
watch -l current_row->enabled_p
commands
bt 10
continue
end
set logging file /tmp/emacs.gdb
set logging redirect on
set logging on
set height 0
cont

Then I started Gnus, entered a group that triggers async prefect,
selected an article, and waited a bit.  Then, when nothing visible is
changing on screen, I get the following output.  (The cursor is
fluttering, though, so that's changing...)

I'm not sure how much to include here...

Hm...   Is wait_reading_process_output triggering this?
