------------------------------------------+---------------------------------
 none of the tamtam activities release the audio device when not using it.
 this will prevent an XO laptop from suspending properly, and may even
 prevent other programs from using the audio device.

 this command can help observe that the activity is doing the right thing:
 {{{
     while sleep 0.1
     do
         egrep 'closed|state' /proc/asound/card0/pcm0p/sub0/status
     done
 }}}
 the output should be "RUNNING" while noise is being made, and "closed"
 when not.
