Here's some info about refcounting... it looks like we need to explore %refcount and %unrefcount

Hm. I don't think it's that simple. The %refcount stuff assumes your C++ objects are refcounted. Which the Ndb objects aren't. Which is why I've been toying with the idea of hooking into the reference counting/gc of the target languages. But that may not be possible in any realistic way.

Indeed, you are right.

There are only a few things that need to get refcounted - Ndb, NdbTransaction, NdbOperation... and even then it's unlikely that you let the Ndb go out of scope. So maybe hooking in language level refcounting wouldn't be too terrible.
