I just choose "clru" because it already exists in our dependency tree thorough gix. I don't think LRU is the best cache eviction policy for our use case (a simpler FIFO-based one might be good enough?), but it wouldn't matter for CLI or GUI use case. I don't see significant performance degradation with "jj log --stat -n1000". RwLock is replaced with Mutex since get() is inherently a mutable operation.
