Is the Pony language's GC a GC then? It runs at determinate times, namely when a behaviour (an actors' receive function, basically) finishes running... and because actors cannot share mutable state, and immutable values with more than one owner can be handled easily by a simple common parent actor, each actor's GC is completely independent of each other. Things are rarely as clear cut as we would want to believe.
