Unless there is a simple, reliable, cheap, and universal solution at hand, consider closing this.  Given how long PyTuple_New() has exist, it doesn't seem to be much of a problem in the real world.

Historically, we punted on "crashers" involving either gc.get_referrers or byte code hacks.  Both of those reach inside Python's black box, allowing disruption of otherwise sensible invariants.
