[O] bug#17055: 24.3.50; Emacs hangs in Org mode file

[Glenn Morris]

Perhaps this is fixed now, according to comments at:

http://lists.gnu.org/archive/html/emacs-orgmode/2014-03/msg01176.html

(It would be great if someone would keep an eye on these Org bugs that
get reported to Emacs and update them when appropriate.

Although it seems better to report Org bugs to the Org-mode list rather
than to Emacs.)

Regarding the "few remaining bugs we want to fix" part, I'd advocate
trying to solve the following 2 bugs as well before merging back into
Emacs:

- #16440: Some colors of the theme aren't respected in latest Emacs
- #15298: Background color lost when highlighting a string

Best regards,
  Seb

Then try to

M-x profiler-start RET RET
<... reproduce ...>
M-x profiler-report RET

And the C-u RET on the + to expand the display.

I think this is a duplicate of 16832.  The same function,
org-mode-flyspell-verify, causes this, and the effect is the same: it
takes Emacs a lot of time to get out of that processing, whatever it
is.

I hope Org maintainers could take a good look on this.
