Sorry I took so long to get back to you.
It turns out Csound is not related to the problem.

In this case I am only using kernel 2.6.33.5-rt23-amd64, alsa lib 1.0.2, 
but 2.6.34 does it too.
I bring up firefox.  Web pages attempt to play sound.   The kernel 
begans doing:

[ 2879.766331] allocate_pipes: ch=1 int=2
[ 2879.766332] allocate_pipes: channel already open
[ 2879.766333] allocate_pipes(1) err=-11
[ 2879.766334] pcm_hw_freed
[ 2.821190] pcm_analog_out_open  cs=0  oc=2  r=44100
[ 2879.821266] allocate_pipes: ch=1 int=2
[ 2879.821267] allocate_pipes: channel already open

,infinitely.  The system is unusable at this point and I have to 
Alt-SysRq-k to get back in.

Let me know what other information to provide.
