that stm paper isn't the end.

there's a java implementation which seems to be exactly what we want: http://research.microsoft.com/~tharris/papers/2003-oopsla.pdf

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.
