Waking up from hibernation seems similar to a reboot where memory is in a fresh unfragmented state.

I expect no one cares, but thought I would post this observation.

It might be interesting for you to note that hibernation has been around, and working essentially the same way for 20 plus years. Hibernation was first introduced by Compaq for portable computers so users can, for example, close the lid to their laptop and it retains the state it was in by saving the contents of the RAM to disk in the hiberfil file. Then the computer can be completely powered off (unplugged and even have the battery removed) and upon the next boot, fully restored to where it was before the lid was closed.

This IS different from a reboot, however. With a reboot, everything in RAM is lost. The contents are NOT saved to disk.
