My Emacs displays its runtime information like this:
  <github.com/shynur/.emacs.d/issues/1#issuecomment-1671815270>
Since it's mainly related to GC, I have it updated after each GC.

I believe I'm not the first person to do this; why others didn't
report the bug may be that they don't care whether the number of GCs
is exactly the same as they expect or one less, so they didn't really
check when `gcs-done' is updated.
IOW, if the update time of `gcs-done' is changed, I think most people
won't notice this change at all.

I'm not a native English speaker.  Does the POST in `post-gc-hook'
mean the functions will run when GC is DONE?

And `garbage-collection-messages'.
