I am concerned about a possible scenario where a user tries to use DirectIO, runs it for a period of time, and experiences some problem on the bookie server side, but is unsure of the cause and suspects it may be related to DirectIO. As a result, the user disables DirectIO and restarts. In this case, data may be lost.
