Is hibernation an argument for orthogonal persistance?

[Jeremy Shaw]

Hello,

Since laptops are now outselling desktops (atleast in the US)[1], I
think it is safe to say that good hibernation support is a valuable
feature of a modern OS.

It seems to me that hibernation (aka, suspending to disk) is really
just a specialized usage of orthogonal persistence. If that is true,
then it seems like it might be worthwhile to fully exploit
persistencce, since many of the hard parts have to be done to support
hibernation anyway.

One obvious difference is that orthogonal persistence needs to not
interfere with normal operation of the machine whereas hibernation can
take a few seconds to do its job.

Just a thought...
