I'm now using rev 115085 (of 2013-11-12), thanks to Dani.

As for 115006, that version is almost unusable as some operations are so slow.

See a comparative demo of rev 114715 and 115085 on
http://screencast.com/t/ITwSR0Wrz.

Problems:

- Moving with C-up/down takes more time with latest Emacs, and uses up to 33%
  of my CPU (vs about 1% with rev 114715).

- S-TAB'ing in an Org mode file takes 20s (vs 1s with rev 114715) and eats up
  to 33% of my CPU as well.

Best regards,
  Seb
