Ahh, hibernation.

Something that is fairly commodity, and yet Linux can't get it right.
QED. Incidentally one of the reasons I don't use Linux as my desktop
anymore.

Pervasive snapshotting is a problem because most apps don't know how
to recover from snapshot. So you're reduced to imaging the entire RAM
to disk. That's slow, given that hard drives are slow.

Hard disk has only gained a 2X speed increase in the last decade,
while RAM has increased what, 10X? imaging a 2GB RAM image to disk
takes about 20-30 seconds.
