bug#15876: 24.3.50; Highly degraded performance between rev 114715 and 1

User-agent: Gnus/5.13 (Gnus v5.13) Emacs/24.3.50 (windows-nt)

Hello,

Having switched from Emacs 24.3.50.1 rev:114715 to rev:115006, I've
noticed a huge degradation of performance -- with the same .emacs file.

See a comparative demo on http://screencast.com/t/grH48ZtIbvI2.

What's become slow:
- movements (<down>, <C-home>, etc.) in Org files
- movements (<down>, <C-home>, etc.) in mails
- maybe other stuff (not yet tested)

What's become VERY, VERY slow:
- cycling in an Org file with <S-TAB>: from more or less 1 to 20
  seconds... Almost impossible to use.

Flyspell is not the culprit (at least, in the Org file): I did disable
it before making the video.

I'm willing to use elp, would I know which packages to instrument.

Best regards,
Seb
