as you can't unshare(CLONE_NEWPID), you might consider doing a
to restart 1 and then restart the container process tree under it, block

that's how we've implemented restart. You might be doing that already,
sorry I haven't had time to look at your code.
1 being an invariant between checkpoint and restart.
