Benchmarks and Intel's recommendation show that aligned allocation is actually important for AVX performance, and NumPy depends on CPython providing the right allocation APIs (for integration with tracemalloc): https://github.com/numpy/numpy/issues/5312 So I think for 3.5 we should start providing the APIs. Whether we use them in Python core is another discussion. Nathaniel, what APIs would you need exactly? See Victor's proposal in msg196834.
