It’s not weird that you can’t share state between totally different processes except by passing in args.

And you can make it thread-like if you prefer by creating a “load balancer” setup to begin with to keep them CPU bound.

    require('os').cpus().length

Spawn a process for each CPU, bind data you need, and it can feel like multithreading from your perspective.
