It takes courage to admit failures like this! I think this is a good call. It echoes the experiences with Unladen Swallow and Pyston. Despite what people may think, CPython really isn't slow, given the large set of constraints on the implementation.

Oh, I still have a long queue of optimization ideas that I want to try :-) But first, I would like to fix the issue blocking all significant optimizations: make the stable ABI usable to allow to change major CPython design choices without breaking C extensions.

Sadly, I didn't find time yet to write a proper PEP for that.
