> Commit logs are not removed after nodetool flush or nodetool drain. This can 
> lead to unnecessary commit log replay during startup.  I've reproduced this 
> on Apache Cassandra 1.2.8.  Usually this isn't much of an issue but on a 
> Solr-indexed column family in DSE, each replayed mutation has to be reindexed 
> which can make startup take a long time (on the order of 20-30 min).
> Reproduction follows:
