Description
This issue may belong in another place but for tracking purposes I added it here.
It would be nice if numpy not only allocated on 32byte or 64byte boundaries, but did so in an official way (often leaving magic markers to the memory just behind the original pointer) that could be hooked.
This would allow a new array memory allocator to hook how numpy arrays are allocated offering features such as array recycling or numa node allocations.
In the future it could be used to allocate arrays that span multiple computers.
