FYI, I independently re-implemented (without knowing) a similar feature
for Org mode (see `org-element--cache-interrupt-C-g' and
`org-element--cache-interrupt-C-g-max-count' in org-element.el)
Note that it is an example when Elisp code needs some cleanup if
emergency exit is requested:

(when (and inhibit-quit org-element--cache-interrupt-C-g quit-flag)
               (when quit-flag
	         (cl-incf org-element--cache-interrupt-C-g-count)
                 (setq quit-flag nil))
               (when (>= org-element--cache-interrupt-C-g-count
                         org-element--cache-interrupt-C-g-max-count)
                 (setq quit-flag t)
                 (setq org-element--cache-interrupt-C-g-count 0)
                 (org-element-cache-reset)
                 (error "org-element: Parsing aborted by user.  Cache has been cleared.
If you observe Emacs hangs frequently, please report this to Org mode mailing list (M-x org-submit-bug-report)"))
               (message (substitute-command-keys
                         "`org-element--parse-to': Suppressed `\\[keyboard-quit]'.  Press `\\[keyboard-quit]' %d more times to force interruption.")
                        (- org-element--cache-interrupt-C-g-max-count
                           org-element--cache-interrupt-C-g-count)))
