Where .restype is set to c_void_p ctypes spots this and returns it as
int32. Where it's set to another callable (e.g. your custom types) it
actually wraps the value by passing it to the callable and returning the
result.

Then, because your custom types are pointers, it stores them in an
appropriate value, and also stops the storage being reused.

I'll test again to make sure that I have this correct, but my tests
yesterday certainly suggested that your patches fixed this.

Thanks,

James
