> It appears that depending on actual cache entry sizes, the {{CacheLIRS}} might grow beyond
the configured limit.
> For {{RDBBlobStore}}, the limit is currently configured to 16MB, yet storing random 2M
entries appears to fill the cache with 64MB of data (according to it's own stats).
> The attached test case reproduces this.
