1/12 Let's talk about posix_spawn, and when to use it.
2/ posix_spawn was reaction to the high cost of fork/exec. It traded off flexibility, and in return, it bought efficient kernel implementations (macOS, FreeBSD, Solaris?), but also permitted user-space implementations built atop fork/exec (Linux).
