[ale] Q: Should Linux swap space depend on number of users?

[Jeff Hubbs]

John -

For all practical purposes, swap is user-agnostic.  It's a mechanism
that the kernel uses based on the memory consumption of all processes,
regardless of owner.  

When I worked briefly with a Linux Terminal Server Project rig, I
noticed that workstations could run different instances of the same app
and each instance took up just a small increment of memory beyond that
of the first one.
