Absolutely. Thanks for having taken time to test it, and report it!

What is a bit weird, though, is that the count number is different:

- you have 2 calls of org-mode and 1 of org-bookmark-jump-unhide
- I have 1 call of both...

Good to hear. I'm using

GNU Emacs 23.1.50.1 (i386-mingw-nt5.1.2600) of 2009-10-14 on LENNART-69DE564 
(patched)
Org-mode version 7.4 (release_7.4.29.gc61cd)

on Windows XP, Media Center Edition, Version 2002, SP3
on Sony VAIO 2-Core @ 1,83GHz with 2,00 GB RAM.

Very similar to your config (at least, for Emacs/Org)...

Best regards,
  Seb
