But if I do this with emacs -Q, and use edebug to step through the
related functions, I can reproduce it there.  It is enough to edebug
just `dired-find-file' and hit SPC, SPC ... for the issue to occur as I
see it.

I was using two different frames for Edebugging and performing the
recipe.

Does this confirm my suspicions that intermediate redisplay may play a
role?

Michael.
