For example, if you record a kmacro which does C-x s, then when you
repeat the kmacro and there are more buffers which could be saved, the
kmacro will hang instead of either completing or erroring.

Straightforward minimal reproduction:

(execute-kbd-macro (kbd "M-: (map-y-or-n-p SPC \"\" SPC #'ignore SPC '(1)) RET"))

This hangs in a loop around read-event and has to be interrupted with C-g.
The loop in question in map-y-or-n-p:

(while (progn
 	(setq char (read-event))
 	;; If we get -1, from end of keyboard
 	;; macro, try again.
          (equal char -1)))

I'll fix this in a followup patch.
