Thanks! This is exactly what I am looking for:

void enif_nproc_schedule_ecall(ErlNifEnv *proc_env,
        ERL_NIF_TERM module,
        ERL_NIF_TERM function,
        ERL_NIF_TERM arguments,
        void (*result_func)(ErlNifEnv *proc_env,
            void *state,
            ErlNProcResultType result_type,
            ERL_NIF_TERM result));

And the concept seems to be very tempting. And talking about this (from
the one slide before the last):

    When will these features show up?
        –Hopefully R15, but this is no promise

Any update? :)

For now, we decided to stick to NIFs and execute C-to-Erlang calls in a
separate thread.
