It's an interesting idea, but it wouldn't do as it is, as I'd need the
ability to create a CObject given a memory location and a size.  Also, I
am not expected to free() the memory, which would happen when the CObject
got GC'ed.

(BTW: I am *not* arguing that PyBuffer_FromReadWriteMemory() should be
exposed by default.  I'm happy with exposing it in my little extension
module for my exotic needs.)
