Uhm, Martin, I think you just said exactly what I said with a lot more
words... :-)

The key parts from Dmitri's example are:

    char* cache = content_new();

and

    amq_content_basic_set_body(content, cache, message->nSize, content_destroy);

So content_destroy is the free_fn, called when the content is actually
destroyed.  Which happens when the last reference to it is dropped.
