How do you detach a linux process?

A developer livestream transcript documenting a deep dive into how to properly detach a spawned child process on Linux to avoid zombie processes. The session covers process trees, fork/exec mechanics, bash's oneshot optimization (where sh -c avoids forking for simple commands), the role of setsid() and double-forking for daemonization, process groups vs sessions, and SIGCHLD handling. The developer works through this in Zig while building a Wayland compositor taskbar/app launcher, ultimately solving the zombie process problem using a double-fork pattern with an intermediate process that exits immediately after exec.
