Ref counting vs GC

See if ref counting could be better than GC.

To avoid freeing too often, we could table the freeing for when a threshold of garbage is reached.

I like the idea of "running gc every frame". That could translate to running small sweep more often rather than potentially big sweeps depending on a threshold.
