Could you explain how virtual memory makes a process more secure?  My intuition is that it would be another source of contention to manage (like CPU, RAM, IO, etc).<p>Maybe you&#x27;re considering non-sequential address space an improvement for security.  That I could see.  ASLR would be another, which, you can see the effect of by multiple runs of t&#x2F;_end.exe in rt0.
