Rebased, has doctests, needs review.

No, I don't think there's a dependancy. Lots of doctest failures, but  
I bet they're all due to the same bug or two. I'll get to it within a  
week.

Sure, link?

We're pretty sure it can be done--proof of concept in the works. We'd  
really like to get this pickling thing out of the way without adding  
ugliness that will never go upstream (and I've always regretting  
letting cruft get in as it seems to never actually get cleaned up  
until it really bites and is a mess.)

P.S. Cool category graph.
