Notmuch/0.18.2 (http://notmuchmail.org) Emacs/24.4.1 (x86_64-pc-linux-gnu)
Sorry, I was being sloppy.
I tried to minimise the problem and enabling flyspell in the XML file
seems to be the culprit. So:
M-x file-find "...xml file I gave you..."
... go to final comment line...
M-; (i.e. M-x uncomment-region)
I did a (profiler-start) with (setq debug-on-quit t) and got this:
- flyspell-post-command-hook 1994 81%
- byte-code 1994 81%
- flyspell-word 1992 81%
- sgml-mode-flyspell-verify 1989 81%
- sgml-lexical-context 1985 81%
- sgml-parse-tag-backward 1985 81%
- byte-code 1985 81%
- forward-sexp 1985 81%
- nxml-forward-balanced-item 1985 81%
- nxml-forward-single-balanced-item 1985 81%
- funcall 1985 81%
+ #<compiled 0xf573b1> 1949 80%
