--------------------------------------

Thanks, Rakesh R.

For Proposal-1, flush error on SyncThread would not cause data loss. if flush 
error happens, we don't roll the log marker, so all the entries are still in 
journal files. these journal files could be replayed when bookie server 
restarted.
                
> EntryLogger doesn't detect when one of it's logfiles is corrupt
