It was easy.  Evaluating this in emacs -Q is already enough:

--8<---------------cut here---------------start------------->8---
(progn
  (defun provoke (&rest _)
    (run-with-idle-timer .001 nil
                         (lambda () (sit-for 2.))))
  (advice-add 'handle-switch-frame :after #'provoke))
--8<---------------cut here---------------end--------------->8---

Just create some more frames and type M-TAB (in your window manger) lots
of times.  After that, timer-idle-list is full of blink-cursor-start
timers.

Michael.
