PEP 445 : Added new API to customize memory allocators in Python
It took to use in CPython, but it is not excluded that it is useful for other purposes.

PEP 442 : Secure Object Finalization
This PEP removes all current tricks and limitations regarding the finalization of the object. With it, objects with __del __ () methods, as well as finally generators, can also be finalized when they are part of the “reference cycle”. According to the new scheme, the object finalizer is always called exactly once. In addition, for this PEP, you will not need to change something in the already written code - objects with existing finalizers will follow this behavior automatically.
