First off, realize that the problem actually happens during suspend-to-ram. Think about that for a second. In fact, think about it for a _loong_ time. Because dammit, people seem to have a really hard time even realizing this. There is no "atomic copy". There is no "checkpointing". There is no "spoon". > Hope this helps. Hope _the_above_ helps. Why is it so hard for people to accept that suspend-to-ram shouldn't break because of some IDIOTIC issues with disk snapshots? And why do you people _always_ keep mixing the two up?
