> CASSANDRA-17056 changed the way we invalidate key cache when deleting 
> sstables after compaction. It now iterates over all the keys in the keycache 
> and deletes the key if it is for the current sstable.
> It can potentially take several seconds per deleted sstable to do this.
> Patch attached which disables this by default, but can be turned on if anyone 
> relies on this.
