live hibernation style checkpoints

Is it possible to lay down a hibernation checkpoint, but keep on working... and then have the computer "unwind" and go back to the previous situation? What I mean by this is if I have 5 browser windows open, and I felt like playing a game that is not very stable, or I have other user's logged in with unsaved work -- i'd like to do the equivalent of hibernate without shutting down. If the computer locks up or crashes, then I can continue where the last checkpoint was.

Is this possible????? Ideas??

I doubt it is possible for the fact that restorinng from an old image could cause issues with the memory knowing about files that either changed, or were deleted.

Now if you don't need to worry about files when you restore back, something like GoBack works well, though you do have to reboot.

I'm not concerned about the files. I'm concerned about the programs running in memory! :-)

VMware can do this, no sweat at all.

And my university (I think -- it's been a while) had some IDE controllers that did the same sort of revert-to original state thing that VMWare does. That is, any changes to the hard drive were made in some sort of scratch space, but when the computer was rebooted, the scratch space was deleted and the computer reverted to how it was the last time it was rebooted. Pretty nifty. I have no idea what the product was, but it worked very well.
