I wasn't able to reproduce under Emacs 27.1

Feel free to let me know otherwise, but I'm planning to wait for
Andras' reply to your note several hours back before I open a bug
report.  It seems entirely possible I've not used the correct settings
in attempting to throttle this.  Moreover, I forgot to commit the
changes to my .emacs, where I'd stuffed this bit:

#+BEGIN_SRC emacs-lisp

;; tweaks for native-comp
;; 
https://ddavis.io/posts/emacs-native-centos7/#deferred-and-asynchronous-compilation
;; via https://github.com/jwiegley/emacs-async/issues/96
;; helper boolean I use here and later in my init.el

(defconst my-using-native-comp
  (and (not (version< emacs-version "28.0"))
       (fboundp 'native-comp-available-p)
       (native-comp-available-p))
  "Indicates we are using native compilation (via libgccjit).")

(when my-using-native-comp
  (message "Native compilation is avialable; throttling")
  (setq native-comp-deferred-compilation t)
  (setq native-comp-async-query-on-exit t)
  (setq native-comp-async-jobs-number 4)
  (setq native-comp-async-report-warnings-errors nil))

#+END_SRC

My .emacs is now updated, here:
