Being backed by swap means : that the data in the memory blocks it's using can be written to swap : if the system decides there's something better to do with that real : memory - just like anything else that's backed by swap.

Now, any idea on how to allocate more than 500m? --Jerry name: Jerry Alexandratos || Open-Source software isn't a phone: 703.599.6023 || matter of life or death... email: jerry@thehutt.org || ...It's much more important || than that!
