Swap space with 12G memory

[James Cooley]

Depending on the situation, you could also argue that you don't want to
deny your services to clients when memory just so happens to be heavily
utilized.  In that case you'd have more swap than you ever think you'll
use, especially since disk space is relatively cheap.

Of course, there are some systems that are so under-utilized ram-wise,
that physical memory will never be filled in the first place.
