Am I annoying people on this list by asking too many simple questions?

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.
