The real reason akode does less skiping, is because I've put in 
madvise/fadvise calls to advise the I/O layer how the disk is going to be 
accessed. When you advise the kernel that the disk is going to be accessed 
sequentially, it increases the read-ahead buffer and discards pages 
immediatly when they are no longer accessed..
