When write-region is called by multiple Emacs instances at the same time.
You can try it by yourself with the latest keyfreq master commit, using this
configuration:

(require 'keyfreq)
(setq keyfreq-autosave-timeout 1)  ;; I'm using 1 second to test the lock
mechanism
(keyfreq-mode 1)
(keyfreq-autosave-mode 1)

After that you can open two instances and try to write in both of then
quickly random
characters in the scratch buffer (you will need to do it quickly and
switching between
both instances).
