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.
