Linux watches the last access time of every page and at some point it
considers a page less valuable than having more cache. At that point
binary code gets dumped and data gets swapped out.
But if the effect is noticeable remains to be tested for a given the
amount of ram and usage pattern. I'm not sure having 4G cache or 4.1G
cache makes much of a difference.
