Isn't there something called demand paging that takes care of that?
it is supposed to do this, but falls short when it comes to startup
performance on rotating storage, which is why we have various platform
specific hacks to do linear reads of all libraries required at startup
in order to hide the seek latencies incurred by demand paging.
It also falls short on avoiding the runtime loader's work on relocations
in data segments, execution of .init sections, etc.
