So I started looking for suspecious timers under audio/*.c and immediately
found this in audio/audio.c :

static void audio_reset_timer (AudioState *s)
{
     if (audio_is_timer_needed ()) {
         timer_mod (s->ts, qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + 1);
     }
     else {
         timer_del (s->ts);
     }
}

static void audio_timer (void *opaque)
{
     audio_run ("timer");
     audio_reset_timer (opaque);
}

Note how that is using a timer which expires every freaking nano second,
I think it is very likely that is the culprit.

Yep, this is the culprit, patch coming up.
