--------------------------------------------------------------------
You should probably move to the SIGINT (or SIGTERM) for a graceful shutdown not
even for caches but for other services as well (e.g. CASSANDRA-3936). But I'm
aware of that problem and I think that if row cache is hopelessly outdated we
don't really want to load it the first place (in current situation or new)
because it would be just a waste of time...

> CASSANDRA-2392 saves the index summary to the disk... but when we have saved
> cache we will still scan through the index to get the data out.
> We might be able to separate this from SSTR.load and let it load the index
> summary, once all the SST's are loaded we might be able to check the
> bloomfilter and do a random IO on fewer Index's to populate the KeyCache.
