> As noted in CASSANDRA-809, we have a certain amount of flush (and compaction) threads,
which mix and match disk volumes indiscriminately.  It may be worth creating a tight thread
-> disk affinity, to prevent unnecessary conflict at that level.
> OTOH as SSDs become more prevalent this becomes a non-issue.  Unclear how much pain this
actually causes in practice in the meantime.
