Cool. Thanks, Nick!I did experiments based on this idea (https://github.com/stephanreiter/cpython/commit/3bca91c26ac81e517b4aa22302be1741b3315622) and haven't rejected it yet. :-)Together with the other fix (https://github.com/stephanreiter/cpython/commit/c1afa0c8cdfab862f409f1c7ff02b189f5191cbe), numpy at least is happy in my Python-hosting app.
