Matt, as to "why it needs to work that way" -- this approach will simply
work well without a need to patch mainline kernel much, since almost everything
needed for transparent restore already in kernel except "ptrace with frozen cgroup",
(we even restore without frozen cgroup but with a couple of nasty tricks in crtools
utility now). But if there some other approach which we've missed, I would
really appreciate if you share it.
