The GC changes PJE is looking at are to make sure you *can* do something about
it. If the generator hasn't been started, or has already finished, then the GC
won't consider it as needing finalisation.
Actually, if a generator has already finished, it no longer holds a suspended frame alive, and there is no cycle (at least not through the generator.) That's why test_generators no longer leaks; explicitly closing the generator breaks the cycle. So the only thing fixing GC would add is cleaning up cycles where a created but not started generator is the only thing keeping the cycle alive.
