Very special thanks to Lee Tibbert, a Scala Native core contributor who brought a wealth of networking experience (and humor!) to this project. In addition to their code contributions, Lee spent countless hours reviewing my PRs, tracing bugs, and upstreaming fixes in Scala Native core. I could not have done it without you!
