    Well, one of us is right and one of us is wrong.  No reason to give up
since this is something that can be empirically proven.  It's a simple
matter of setting up a proper test to convince the other person.  Such
as this:

    Killing off one of the zsh processes with an RSS of 2064 changed the
free RAM (+buffers) from 352036 to 352676 for a change of 640kb instead
of the anticipated 2064kb.  You're right.  See?  Painless.
