bug#65025: Possible race in make-frame

[Anders Blomdell]

When running

  /usr/bin/emacsclient --eval '(make-frame)'

it sometimes (often) opens up a small window (10x21) instead of the expected 
40x80 window.

Setting a hook for after-make-frame-functions like this:

(progn
  (setq after-make-frame-functions nil)
  (add-hook
   'after-make-frame-functions
   (lambda (frame)
     (let ((width 80)
           (height 40)
           (start-width (frame-width frame))
           (start-height (frame-height frame))
           (visible (frame-visible-p frame)))
       (print (format "Start %dx%d %S"
                      start-height start-width visible))
       (if (not visible)
           (progn
             (while
                 (not (frame-visible-p frame))
               (progn
                 (sleep-for 0.001)
                 (print (format "X %dx%d"
                                (frame-height frame)
                                (frame-width frame)))
                 ))
             (sleep-for 0.001)
             (print (format "Resetting %dx%d -> %dx%d"
                            (frame-height frame) (frame-width frame)
                            height width))
             (set-frame-width frame width)
             (set-frame-height frame height)
             (sleep-for 0.1)
             (print (format "Resetting %dx%d -> %dx%d"
                            (frame-height frame) (frame-width frame)
                            height width))
             (set-frame-width frame width)
             (set-frame-height frame height)
             )
             )
         )
       (print (format "Done %dx%d"
                      (frame-height frame)
                      (frame-width frame)))
       )
   )
  )



usually has two different outcomes:

  "Start 10x38 t"
  "Done 10x38"

or

  "Start 40x80 nil"
  "X 40x80"
  "X 40x80"
  "X 40x80"
  "X 10x21"
  "Resetting 10x21 -> 40x80"
  "Resetting 40x80 -> 40x80"
  "Done 40x80"
