FWIW, that is not the part of the code that gets executed when there is a crash.
However, the branch of the `if' that is executed when there is a crash also has
a similar `save-window-excursion':
(save-window-excursion
(select-frame frame)
(setq empty-buf-p (and (= (point-min) (point-max))
(one-window-p (selected-window)))
specbuf-p (and empty-buf-p
(special-display-p
(buffer-name (window-buffer))))))

And just what code do you suggest for going off to do something on a different
frame and returning? AFAIK we do not have a `save-frame-excursion'. I have
always considered (and seen) `save-window-excursion' to be the way to do this.
