Over 20 benchmarks fail to run on Python 3.14.0

After updating to Python 3.14.0, more than 20 benchmarks fail to run that did not occur in previous versions (e.g., Python 3.13.x). This issue was reproduced on Win 11 with AMD and Intel processors.

Will this issue be addressed or fixed for compatibility with Python 3.14?

For reference, 3.15:

22 benchmarks failed:

@hugovk @diegorusso I reran the whole suite on 3.14 and 3.15-dev, and all seems to be good now, unless I'm missing something:

#417 was merged earlier, thanks for testing!

All seem good:
