I made a big progress on this one. I realized that Emacs did not into an infloop, but simply gave me back control after a very long time (more than 2 mins). Good news #1. I thought at using the profiler of Emacs 24, and it gives meaningful results. Good news #2.

Text mode + all my config (enabling Flyspell by default) is OK, (from 0:07 to 0:14, then undoing the changes) 2. Org mode + all my config (enabling Flyspell by default) is NOT OK. (from 0:40, blocking at 0:49, giving control back at 3:15) Best regards, Fabrice PS- Org-mode version 8.2.5h (release_8.2.5h-733-gd55438)
