Nope. In Unix, a process is killed when its parent process exits. This is one reason why you shouldn't launch application processes directly :) Instead, use NSWorkspace to launch the app (or call LaunchServices directly if you prefer a C API.) This starts it up in the normal way, as a subprocess of your login session’s main launchd process.
