Why didn't you just check yesterdays articles in auxtex-devel? (c;
might be interesting.

Also, Robert wrote in private mail that due to the size of his file it
would take some time to come up with a minimal example.  This is what
I wrote in reply in order to generate some more information for
preparing an example:

| Maybe it helps to profile Emacs before you go through the hassle of
| preparing a minimal file.  In order to do this, start Emacs, load your
| LaTeX file, switch to the *scratch* buffer, copy the lines
| (elp-instrument-package "font-latex-")
| (elp-instrument-package "font-lock-")
| into the buffer and type `M-x eval-buffer RET'.  You can then start
| editing your file.  When the slow-down starts, leave Emacs running for
| two or three minutes and then type `M-x elp-results RET'.  The output
| should help us identify the functions causing the problems.  Then it
| might be easier to create a minimal example file.
