There's already a Python implementation of what's described in the 
paper.  It's called ZODB.  :)  Just use the memory backend if you don't 
want the objects to persist.

Granted, if you want automatic retry you'll need to create a decorator that 
catches conflict errors.  But basically, ZODB implements a similar 
optimistic conflict management transaction algorithm to that described in 
the paper.  Certainly, it's the closest thing you can get in CPython 
without a complete redesign of the VM.
