Thanks! I refreshed your PR on top of the Eio PR such that we can merge yours asap :) I'm pretty happy with the new benchmarks, as they show that multicore usage isn't slower than singlecore under contention! Could you clean up the commit history, add an entry to the changelog, ... and take a look at the https://github.com/mirage/irmin/blob/main/src/irmin-pack/unix/lru.ml#L32 to remove the data-race there too? |

This PR aims to change the existing hash tables of irmin and use
Kcas_datahash tables instead.This should help maintain good performances when using irmin on several domains, by replacing the existing mutexes.
