Very interesting, thanks.  It subclasses NSTextView.  It is quite slow
compared to Terminal.app.  For example, I ran one of my favorite
terminal benchmarks: "time cat /usr/share/dict/words" with the
following results:

Terminal.app: 0min 27.8sec
iTerm: 4min 16.9sec
xterm (through XDarwin): 2min 53.6sec

And just for comparision, xterm on x86 Linux: 0min 2.3sec

Of course, the slowdown may not be in NSTextView.  Scrolling in iTerm
is quite fast.  I like the tabbed windows, too.
