ctypes code scares me with its duplication of the contents of system
headers.  I understand its use as a proof of concept, or for hacks one
needs right now, but can anyone seriously propose using this kind of
code in a Python program?  For example, this seems much more
"Linux-only", or possibly even "32-bit-Linux-only", than "unix-like":
