Same as now_cpu_time(), but for fast queries (less accurate) Relies on now_cpu_time() and now_mono_time_fast() is used as a cache expiration hint to prevent now_cpu_time() from being called too often since it is known to be quite expensive. Depends on commit "MINOR: clock: add now_mono_time_fast() function"
