I've tried running without pulseaudio installed, and with the vanilla xfce4-volumed (Debian testing version - 0.1.13-3). The results are similarly gloomy: top by %MEM and by %CPU:
Attached is a tarball containing the /proc/PID/maps output for these two processes, along with the output of hwinfo.
Also interesting is that although I'm seeing this problem on this MacBook Pro, I don't have the same issue with my PC desktop at home, so there is certainly some hardware issue connected to this.
