Well done! xturtle.py is a truly impressive re-implementation and 
enhancement. I ran all of the demos without problems on a Linux (Ubuntu 
Dapper) machine and was very impressed with the speed, as well as the 
number, variety and quality of the demos.

I would certainly think that (after testing ;) ) xturtle might replace 
the current turtle.py. I had also been thinking about what would be 
involved in porting turtle.py to Jython and your refactoring makes that 
a much more appealing possibility.

I saw that you were presenting at EuroPython - best of luck with that 
presentation. I'll be presenting on Python programming at NECC, a 
national educational computing conference, on July 7, so if you don't 
mind I will mention xturtle then.

One final thought - even though the file is large, I would consider 
including at least some demo code in the file itself. Maybe it's just 
me, but I like the idea of being able to demo the module even if it gets 
separated from all other files in the package. Things like that can 
happen. :)
