> Commit of HBASE-4078 added some extra StoreFile verification which just did
> an open of a StoreFile reader and then closes it, ensuring there's no
> exception. If evict-on-close is on, which it is by default, this causes all
> blocks of a file to be evicted even though it's still open.
> We need to add the boolean into the close call in the way we have booleans
> for cacheBlocks at some point since we need to make localized decisions in
> some cases.
> In lots of places, we can always rely on cacheConf.shouldEvictOnClose() so
> shouldn't be too burdensome.
