This problem is non-trivial and a plain pickle solution will fail. You may 
want to try ipython, which is a better interactive command-line environment 
than the default one and has _limited_ save/restore abilities. I tried using 
pickle but failed, so until I have time to dig deeper into the problem I 
implemented a log save/replay option which while admittedly imperfect, in 
many cases is a reasonable solution.

You'll find ipython at:



ps. Some of ipython's nicest features only work in a proper terminal which 
Windows lacks, so you'll need either a Unix environment or the Cygwin system 
under Windows. However the basics stuff is all there under windows.
