idle feature request

[Rustom Mody]

Context: 
I am using idle for taking python classes.

Finish the class and run out usually in a hurry and forget to save the
idle interaction window. Would like to save it so that I can mail it to the students. 

In emacs I could set a hook to make arbitrary 'buffers' like the python-idle
shell become 'saving-buffers' like typical file buffers.
ie in emacs like most other editors, a modified file is ask-to-save
The same can be setup for other (non-file) buffers like a python interaction shell

Can I do the same for idle.

[Note it would be great to have this feature in idle but I am only looking for
a hand in where in the idle sources I an fudge a patch for my own use
