I tried and failed to reproduce the problem.
In a private communication (I hope he reposts it to the list), the OP
said that he *had* turned on debug-on-quit (he misspoke when he said
debug-on-error) but there was no backtrace when he pressed C-g (that in
itself indicates a problem, either with emacs or with the OP's setup.)
He mentioned that he was using a derived mode, so I tried to reproduce
the problem with the following minimal org file:
--8<---------------cut here---------------start------------->8---
(add-to-list 'load-path "~/src/emacs/org/org-mode/lisp")
(add-to-list 'load-path "~/src/emacs/org/org-mode/contib/lisp")
(require 'org-loaddefs)
(define-derived-mode ndk-mode org-mode "ndk")
(add-to-list 'auto-mode-alist '("\\.ndk$" . ndk-mode))
--8<---------------cut here---------------end--------------->8---
I copied an org file (albeit a small one: 15K - I don't have anything
as big as the OP's 3Mb file) to foo.ndk and started emacs with
emacs -Q -l /path/to/minimal/min.org.el foo.ndk
Everything works as expected and I don't get a hang/inf-loop or any
other problem.
It may be that hack-local-variables takes a long time to process a large
file, although I don't think so: iirc, it limits itself to a tail of the
file of a given size, or the last "page" of the file (demarcated by ^L),
whichever is smaller.
Does CPU utilization go to 100% (on the core that emacs is running on)
when emacs is unresponsive? Does emacs -Q with a minimal org file as
above solve the problem (i.e. is the problem with the OP's .emacs)?
Questions, questions...
