I backported the change to emacs-27 branch locally and tried a simple
test using our real-world emacs module against it and the change seems
to fix the memory leak. Our module (and the test I tried) is written
in ocaml (calls to/from emacs are via C bindings) and relies on
interplay between ocaml and emacs gcs to not leak memory, so that
working is a good sign.

Compared to emacs-26, it uses a bit more memory, but I think that is
expected. The main thing is that memory is stable.
