[erlang-questions] Managing object lifetimes from NIF

Hi All,

Is it possible to safely retain references to objects like an
ERL_NIF_TERM inside a NIF resource?

For instance, can I have

struct myresource {
	ErlNifPid *pid;
	ERL_NIF_TERM *term;
};

and allocate this structure with enif_alloc_resource in such a way that
I can ensure (either implicitly or explictly) that pid/term are properly
reference counted till at least the dtor is called on my resource?

Thanks!
-Greg
