There are two benefits:
a) it doesn't need to access the hardware.
b) avoid the syscall by using vdso clock_gettime().
The cons is the CLOCK_MONOTONIC_COARSE returns the time at the last
tick.
Is this something desirable for PulseAudio? This could impact the
timer-based scheduling, I'd rather keep the precision here.
