Well, the third thing was just my reasoning for asking in the first place.  
I need to be able to acquire/release shared resources reliably, like an  
OpenGL texture, for example.

Come to think of of though, I haven't thought this issue through with  
regard to multi-threaded rendering, so I guess I'll have to think of  
something more clever than a ref-counted texture..
