No problems with the testing. get-lru-window never returns a dedicated
window, so this can be simplified to:

  (let* ((predicate
          (or (cdr (assq 'frame-predicate alist))
              (lambda (frame)
                (and (not (eq frame (selected-frame)))
                     (get-lru-window frame)))))
