Actually, the Cocoa text control is the source of the editor's lag.
A quick Shark test will show you that (just let Xcode preprocess
a nicely templated C++ file that includes <Carbon/Carbon.h>
to get a nice test case of a large text file), just like it will show
you that the beachball you see after changing a build setting
in a project with a couple of 100 files comes from Xcode's
dependancy analysis (if I understand the function names correctly, that is).
