Was there a recent update to the project? I think the state-of-the-art on this (on Linux) is libsoccr (from CRIU) that uses Linux kernel support for tcp checkpoint-restore. If you're ever for real doing that, you'll need some serious plumbing to make sure your tcp socket is doesn't get updated under your nose while you're checkpointing it. Hint: it involves qdiscs, ifb and netlink. Fun project. I keep hoping one day I'll be able to do the checkpoint operation in one chained io_uring op series :-)
