I use this for one of my systems because I suspend it to swap with
tuxonice and I'd like to be able to suspend even if I've got some stuff
swapped out. Also it has oceans of disk space so a few tens of Gb blown
in swap is really not a problem (or even noticeable).

(You *can* suspend to a file on the filesystem, but it's much more
complex to set up.)
