    Right, but with things like interlocked lists, you can make that
    CPython|background_IO synchronization barrier much more performant
    than relying on GIL acquisition.

    I think we'll have to agree to disagree at this point; there's not
    much point arguing further until there's some code+benchmarks on
    the table.
