> I've been running ITBLLs against branch-1 around HBASE-13616 (move of 
> ServerShutdownHandler to pv2). I have come across an instance of dataloss. My 
> patch for HBASE-13616 was in place so can only think it the cause (but cannot 
> see how). When we split the logs, we are skipping legit edits. Digging.
