I think we're talking about different things. I was talking about
making the kernel very aware of the whole hibernation thing and
tidying up everything in VM before actually going into
hibernation. This, however, would most likely mean that one would have
to have as much swap as physical memory and can't use more VM than
available swap space at the time of hibernation. (This is not unlike
VM under old SunOS, IIRC.)
