Notes

Piège sous-jacent à mach_timebase_info. libsystem_kernel met typiquement la valeur en cache après le premier appel, de sorte que les invocations suivantes sont de pures lectures en espace utilisateur. Le piège existe parce que l'exposition de la base de temps via la commpage est postérieure à l'API.

Détection

Provider mach_trap de DTrace ; attendez au plus un déclenchement par processus.
