Alternative to swap partition: swapfile

Hi,

   > Alternative to swap partition: swapfile

Note that it won't work on XO-1, because jffs2 doesn't support
shared writable mmap(2).

Works on XO-1.5, though, and is as efficient as using a partition for
swap, with the distinction that you need to use a partition instead
of a file if you want to do suspend-to-disk.  (We don't, by default.)
