The problem is that in many places, the Magic functions access shell 
attributes directly (since it's a mixin).  A boundary needs to be drawn 
between the two.  Same for logger.  This is easy, it just needs to be done 
carefully to make sure all codepaths are taken into account.

There's your first project.  Send me a patch :)

I saw that, thanks.  But I (Fernando Perez) wrote ipython, not Francois Pinard 
(though he has sent me useful ideas and comments in the past). :)
