Hmmm, that could be tricky. Have you tried using os.read()?
If you're lucky, Python will be using a malloc() call or
equivalent to create a str/bytes object to read the data
into, and that will return something platform-aligned.

If you're unlucky, there's probably no pure-Python
solution, and you might need to write a small C or
Cython module to accomplish this trick.
