In fact, I'm reasonably sure its meant to be  more like a "swap backed FS"
which just -happens- to be cached in RAM.

I used to configure very minimal swap on machines w/ large amounts of RAM
- why bother with lots of swap? If the app server has to start paging
then performance will bottom out very quickly! - however then tmpfs'es
started showing up in Linux and these want more swap space so long-held
temporary files don't hold up precious RAM.
