And can it similarly lock down for a long time? Or does it unfreeze quickly? What about other major modes? If you create a big JS file and try the same experiment in js-mode? Or create a long Elisp file and do the same in emacs-lisp-mode (you can copy-paste a lot of time the contents of some existing file)? Or take any of those files, switch to fundamental-mode and do the same. Does scrolling also lock up in a similar manner?
