    * Writelock is dropped and reacquired every BLOCK_DELETION_INCREMENT to
    * ensure that other waiters on the lock can get in. See HDFS-2938
    *
    * @param blocks
    * An instance of {@link BlocksMapUpdateInfo} which contains a list
    * of blocks that need to be removed from blocksMap
    */
