using CRIU to checkpoint a kernel build

CRIU stands for Checkpoint/Restart in Userspace. As the criu package should be landing in Utopic soon, and I wanted to test drive it to see how it handles.

I thought of an interesting example of being in the middle of a linux kernel build and a security update needing to be installed and the machine rebooted. While most of us could probably just reboot and rebuild, why not checkpoint it and save the progress; then restore after the system update? I admit its not the most useful example; but it is pretty cool nonetheless.
