If you know something better than another person, why not explain it, instead 
of ridiculing. By the way I do know that calling mmap on an object and 
accessing it will dynamically bring in data in pages, as they are accessed. In 
my previous comments I was referring to the fact that in my view there was no 
simple way of dynamically putting hard restrictions on the amount of data 
cached by kernel for a particular file.
