I keep so so so many opencode windows going. I wish I had bought a better SSD, because I have so much swap space to support it all.

I keep thinking I need to see if CRIU (checkpoint restore in userspace) is going to work here. So I can put work down for longer time, be able to close & restore instances sort of on-demand.

I don't really love the idea of using VMs more, but I super love this project. Heck yes forking our processes/VMs.

CRIU is great for save/restore. The nice thing about CoW forking is it's cheap branching, not just checkpointing. You can clone a running state thousands of times at a few hundred KB each.

You could throw this on a VPS or server and it could help in that regard: (disclaimer, my thing)
