Does Emacs have limit option to not load packages over specific memory? Today I was waiting 1 hour for garbage collection, two times, before I killed Emacs. And M-x memory-report never returns as well. Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M. Stallman https://stallmansupport.org/
