Notes
Les PIDs sur macOS sont 32 bits, attribués de façon incrémentale et bouclent à PID_MAX (99999 par défaut). L'appel est implémenté façon vsyscall en cache dans libsystem après le premier usage, donc les appels suivants ne passent plus par le noyau. Après fork(), l'enfant voit son nouveau PID et le parent conserve le sien.
