I agree it's an issue, I just don't think it's an issue of sufficient
importance that it needs to be solved in the 8.0.x timeframe.

In any case, I'll take a look at developing a patch to replace ARC with
LRU. If it's possible to solve sequential flooding (e.g. via some kind
of hint-based approach) without too much complexity, we could add that
to the patch down the line.
