+ * Currently it is the Connection's responsibility to persist the incoming
+ * flowFiles to the FlowFileRepository. Upon restart the FlowFileRepository
+ * checks the persisted database and moves every FlowFile into the Connection
+ * that persisted it (if it can find it. We could have a different flow, in
+ * which case the bastard FlowFiles are deleted.)
Review comment:
I would call these flow files 'orphaned' instead of 'bastard' (which
sounds like you are angry at them)
