Re: Org file rendering/manipulation too slow

[Bernt Hansen <bernt@norang.ca>]

I think it's something like this:

It's a variable not a function.  I think it controls how much stuff is
written out via (message ...) calls in the implementation of font lock
code on your mac version of emacs lisp.  Calls to message are slow and
there are lots of them in this implementation.  This is just making it
skip these calls.

If anyone has better information than this speculation please chime
in :)
