GH-90997: Shrink the `LOAD_GLOBAL` caches by brandtbucher · Pull Request #102569 · python/cpython
Nothing too clever here, just using 16 bits for module versions instead of 32. LOAD_GLOBAL still has no failures after this change.
Benchmarks came back very slightly negative, but I believe that's just noise (the results are being pulled down by several benchmarks known for their instability).
