Good to hear, even though I didn't write it... :)

Why? You take away from the memory to create a swapfile to swap pages from memory? I think that's a bit redundant, not to mention wasteful. That's like creating a RAM disk to put your WinSlows 3.1 swapfile on.

Well, that might be nice, but it is rather useless.
