From the perspective of a new FFI API user, these are all valid
questions with no immediate/clear answer:
- What would happen on subsequent ffi_lib call? Will it append, or
will it overwrite?
- Is that even legal? If legal, is that a good practice?

I know I had those questions when I was starting using FFI. :) And I
was bugging Wayne with such questions as well... :)

Looking at the ffi_lib code now, it is clear that subsequent ffi_lib
calls are not good. Well, maybe we should make that totally explicit,
and just don't allow to call ffi_lib the second time?

Thanks,
