Ah, that makes sense. FWIW, I stopped using swap partitions a couple of years
ago when I started using SSDs. Neither my laptop nor my desktop have a swap
partition; I just made sure I had more than enough RAM. 8GB in the laptop,
16GB in the desktop. I can't use hibernate because of this, but that doesn't
bother me.
