[Python-Dev] cpython: Tighten-up code in the set iterator to use an entry pointer rather than

[Maciej Fijalkowski]

python is developed. If the change (unreviewed, just randomly applied)
causes crashes, then surely it should be reverted first and continued
on bug tracker instead of lingering (and the complain sitting on bug
tracker)?
