There is no direct equivalent to SIGCHILD on Windows. The closest we can get is monitoring a specific process, given a known pid. On Unix there is no single solution to be able to do that in LibCore's EventLoopImplementationUnix. For Linux there's a SYS_pidfd_open syscall that can integrate into poll(), but on macOS a kqueue would be needed. Given macOS uses EventLoopImplementationUnix for the headless view implementation, we currently can't create a fully cross-platform abstaction at the Event Loop level to match what Windows needs to do. ProcessMonitor's purpose is to abstract away the Unix vs Windows behaviour avoiding more inlined ifdef soup in ProcessManager.
