SubjectRe: New Feature Idea: Compress swap file

Swapping to a file on an ext2 file system is considerably slower than using
a swap device. Using a compression method that is designed for file access
(large chunks of data being stored for long periods of time) probably isn't
going to be very efficient for swapping (4k blocks of data that are stored for
short periods and require fast access).

Maybe just simple RLE is the way to go?
