Stefan, this is the result of your code from 13 years ago in
server.el:

  (when (> (recursion-depth) 0)
    ;; We're inside a minibuffer already, so if the emacs-client is trying
    ;; to open a frame on a new display, we might end up with an unusable
    ;; frame because input from that display will be blocked (until exiting
    ;; the minibuffer).  Better exit this minibuffer right away.
    ;; Similarly with recursive-edits such as the splash screen.
    (run-with-timer 0 nil (lambda () (server-execute-continuation proc)))
    (top-level)))

I could understand the rationale with the minibuffer, but I don't
think I understand why the recursive-edit scenario needs the same
treatment.  Can you explain?  In the recursive-edit case (unlike the
minibuffer case) it sounds like a too drastic measure to me.
