    This patch introduces an ASYNC IPU policy.
    
    Under senario of large # of async updating(e.g. log writing in Android),
    disk would be seriously fragmented, and higher frequent gc would be triggered.
    
    This patch uses IPU to rewrite the async update writting, since async is
    NOT sensitive to io latency.
