["Stu Hood (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12802468#action_12802468 ] 

Stu Hood commented on CASSANDRA-717:
------------------------------------

+1... it's an improvement, although if we can find a good excuse to give the components of SS (AES, Gossiper, Streaming) an abstract base class and lifecycle, that would probably be ideal.
