I'm not really opposed to implement an aligned allocator on top of an
existing allocator. I only propose to discuss that in a separated
issue. I wrote "PEP 445 -- Add new APIs to customize Python memory
allocators" to implement tracemalloc, but also because I was working
on a Python version patched to use custom memory allocators, different
than malloc()/free():
https://www.python.org/dev/peps/pep-0445/#rationale

IMHO only users of PyMem_SetAllocators() would need such "fallback". I
expect all modern platforms to provide a "aligned" memory allocator.
