   Hmm, the benchmark results are not stable from run to run. Even benchmarking 
the main branch against itself gives a randomly and changing set of regressions 
and improvements. I tried on two very different computers: 2021 MacBook Pro 
(Apple M1 Max) and a 2019 Lenovo T490s (Intel Core i5-8365U). Different 
absolute numbers, same large jitter.
   
   Is there some trick for getting stable numbers?
