As an idiot from user space only: why is layout randomization
still something desirable now that kernel and user address space
is totally, cleanly and completely separated, and caches etc. are
flushed upon context-switches and system calls? It is like that,
right?
Also, i was always curious whether there were any runtime costs
implied due to the massive splitting of object files, i wondered
whether that negatively affects the cache "hotness" in any way.
As a programmer i always tried to keep things as compact as
possible.
