Without a freezer, how would you ensure that other processes don't mess up your memory state while you're saving/reloading the image?

It's really just paranoia, particularly for where swapfiles are in use. While developing the swapfile support, I had a couple of occasions where I messed up my superblock because of a bug. I'm very confident now that the suspend code itself is stable and mature, but since the device drivers aren't there, I'd rather not remove the safety nets just yet.
