> org.apache.zookeeper.server.PurgeTxnLog deletes old data logs and snapshots, 
> keeping the newest N snapshots and any data logs that have been written since 
> the snapshot.
> It does this by listing the available snapshots & logs and creates a 
> blacklist of snapshots and logs that should not be deleted.  Then, it 
> searches for and deletes all logs and snapshots that are not in this list.
> It appears that if logs are rolling or a new snapshot is created during this 
> process, then these newer files will be unintentionally deleted.
