[olug] adding swapfile

[Will Langford]

That'd be it.

Dunno if I like a swap file being located anywhere in a 'tmp' directory
where some root-permissioned script might want to delete it, though.

And it'll get ya around 12GB of swap.

You'll prolly need a startup script or add it to fstab or something to get
it to be used after reboots as well.
