    Well, it's not really apples-to-apples because swap-to-RAMdisk
    is copying to a chunk of RAM with a known permanently-fixed size
    so it SHOULD be faster than swap-to-hypervisor, and should
    *definitely* be faster than swap-to-in-kernel-compressed-RAM
    but I suppose it is still an interesting comparison. I'll
    see what I can do, but it will probably be a couple days to
    figure out how to measure it (e.g. without accidentally measuring
    any swap-to-disk).
