IMNSHO, if you have tens of different buffers, you need something more
efficient than buffer cycling ... well, there is no accounting for
taste.

Use `C-/' for undo then.

The way to find this out is by looking at the definition of functions
which already do this, like `repeat'. After cursory skimming it, I'd
say offhand that for your purpose it is sufficient to tinker with
`last-input-event', `read-event' and `unread-command-events'. For
instance:
(defun my-bs-cycle-next ()
(interactive)
(let ((dont-stop t))
(bs-cycle-next)
(while dont-stop
(let ((last last-input-event)
(event (read-event)))
(if (eq event last)
(bs-cycle-next)
(push event unread-command-events)
(setq dont-stop nil))))))
(define-key global-map (kbd "C-c b") #'my-bs-cycle-next)
