> The memtable created by replaying commit logs on startup is supposed to be flushed as
a SSTable before the commitlog is removed, but this is not happening.  So you can lose data
by doing the following:
> 1. insert data
> 2. restart cassandra (using kill, to force replay)
> 3. restart cassandra again
