Attached are:
vmstat: `vmstat 1` output continuously from the beginning of the test (includes several stuttering periods)
meminfo: /proc/meminfo output of three times when I heard it stuttering (XMMS doesn't stutter continuously but it has stuttering periods that last a few seconds - I hope I catched the right moments)
