rust-pyo3: exposition of AncestorsIterator...
rust-pyo3: exposition of AncestorsIterator Compared to the early experiments, we have one less `RwLock` in the wrapping. Still that is somewhat redundant with `UnsafePyLeaked` being itself some kind of lock. In the original rust-cpython code, we were borrowing the `RefCell` with a method that can panic. Instead we are now converting the `PoisonError` that unlocking a `RwLock` can produce. Since all methods acquiring the `RwLock` are themselves protected by the GIL and do not release it before returning, nor do they leak RwLock guards, there is no risk of contention on these locks themselves.
