I only have 1 patch, and since I don't speak rust I have very limited
feedback. Having to use out-of-line functions seems sub-optimal, but
I suppose that's a limitation of the Rust-C bindings.

Afaict this is like C++ shared_ptr<> and using refcount_t seems okay for
that, not sure what else you're asking.
