Not all. For example, when a program object is loaded, the system can 
load only the first page. Then other pages are loaded as the result of a 
page fault referencing addresses in those other pages. This works in part 
because the internal structure of a PDSE is based upon 4K pages.

At least, I *think* that's what it does.
