A reductionist operating system theory? Have you ever heard of emergent 
properties? A system comprised of pieces can as a whole exibit other 
characteristics than the basic elements would provide.

I think it is wrong to use the same small things for big things. You 
would not tow a tanker with your bicycle. Similarly you could use small 
pages for text files but huge page sizes when you need to transfer 
gigabytes or terabytes of memory. Its wrong to dictate ones size fits 
all. (Memories of my relatives in the eastern bloc surface but I better shut up.)
