Unrelated, but somewhat similar in higher level, you can transfer state with durable execution, e.g temporal.io.

Instead of RAM, program's state saved in DB and execution environment resume in the previous state when restarted

How does such a method retain things like open network connections that have significant kernel state involved as well?

[dilyevsky]

it does not. all the state that you need to make "durable" needs to be explicitly committed in temporal via their sdk
