In general using STM for shared state concurrency in everything is mutable
languages like python seems to be destined for failure. Haskell and Clojure
both limit mutability and can use STM effectively. The C# team put
extraordinary effort into doing a STM for the CLR and failed miserably.

It looks like we need to either port the object level locking capability of
the JVM and CLR to python to kill the GIL or python needed new semantics
around mutability.
