Strangely enough, it's not a software feature, it's a hardware one, a feature enabled on certain motherboards, to be exact. The reason why I surmised that Apple's switch to the Intel platform might give them this feature is because of the necessity of the redesigned motherboard that would go along with it, not to mention all those who might buy the OS and use it on a non-Apple designed PC that ordinarily supports hibernate.

Actually, I liked VMS error recovery during a power failure best of all.
When we had people connected to a VAX and had a power failure, and then when the power came back, all they had to do was log back in and type "EDIT/RECOVER filename" and not one keystroke during an edit session was ever lost. The memory planes were battery backed and good for two weeks.


There are research operating systems which can do this with the state of the entire system, without battery-backed memory. You can yank the plug while they're humming away, and when they come back, everything is exactly as it was when power went out, give or take three or four seconds.


Won't be long till we see this in PCs then.
