[issue21351] refcounts not respected at process exit

Tim Peters added the comment: I think Antoine is right on all counts. The most surprising bit may be that p, c, and c2 are in reference cycles, but - surprising or not - that's always been true. The reason "it worked" before 3.4 is that CPython happened to break the cycles via the nasty hack
