Hi,

I am seeing even more aggressive memory usage with recent master branch
commits (at least I think this only started in the last month or so).
Here is a screenshot that shows over 3 GB of
RSS. https://ftfl.ca/misc/emacs_memory.png

This was running commit 06726f6 from today on 12.0-RELEASE-p8.  I run
Gnus, erc, look at an occasional PDF and edit text.  I haven't visited
any extremely large buffers recently.  Garbage collection is happening,
but it does not seem to help.  But, when I call `garbage-collect'
manually there will be a long pause if I haven't called it recently,
then the memory will usually go down to something between 100 and 400
MB.

I just ran your lisp snippet a few times within a minute or so and
without really doing much it reports values between 36195 and 244723 and
it seems to be growing.

If there is an open bug, I will add this information.  If there is not,
I will open one.

Regards,
