I think the entire NSTextView is getting updated with the coloured log.
It's the case where I first observed ConTeXt being slow on the Mac. With
all those duplicate mapfile warnings:

   Warning: pdfetex (file /usr/local/TeX/texmf-local/fonts/map/context/
   pl0-ams-cmr.map): entry for `pltt10' already exists, duplicates ignored

...iTM gets progressively slower.
(yeah, yeah, if I just get my mapfiles sorted, things would be nicer)

It does do some sophisticated things, with line numbers becoming hyperlinks.

Oh right, I forgot:
  21 secs on SciTE Mac/X11 (my dubious build)

Oops, yeah, that one. 9 seconds, if you can believe.
