Yes, tedious and slow, *and* minimally invasive in the kernel. Once we have a tedious and slow process, we'll have some really good points when we try to push the next set of patches to make it less slow and tedious. We'll be able to describe an _actual_ set of problems to our fellow kernel hackers.
So, the checkpoint-as-a-corefile idea sounds good to me, but it definitely leaves a lot of questions about exactly how we'll need to do the restore.
