I read the white page of you prefetch in kernel.

Your tool and the readahead tool are usefull when the configuration 
doesn't change and I think it is a good enhancement on small computers.

The benefit of preload is that it change with the user experience.
Moreover, it doesn't load files which have possibly no chance to be used.
