bug#43389: 28.0.50; Emacs memory leaks

[Thomas Ingram]

Hello.

I experienced something similar today, I noticed Emacs was using 3.6GB 
of memory under light org
mode usage (dozen buffers, all files smaller half a MB). I had to close 
Emacs as my computer was
locking up, but here is my emacs-report-bug output with roughly the same 
workload open.

I'll try to gather more information next time I notice unusual memory usage.

Thanks.
