See: https://github.com/ziglang/zig/issues/17851
Users were noticing that frame render times got slower over time. I
believe (thanks to community for pointing it out) that this is the
culprit.
This works around this issue by clearing and reinitializing the LRU
after a certain number of evictions. When the Zig issue has a better
resolution (either rehash() as a workaround or a better hash
implementation overall) we can change this.
