It seems here's what kills the body editor performance. Luckily, it
seems it should be easily fixable.
Here's what I got from profiler:

So it seems we spend WAY too much time in canonicalizeSett
ingName (600000 calls!).
I got this by opening the default document and typing lots of stuff.
It actually got slow enough that leo hanged and I had to kill it.
If you are using ipython, you can test this by:
%run -p launchLeo.py --gui=qt
Type lots of text in body, and kill leo.
