I have been suggested (thanks David!) that, given CMUCL's cooperative
multiprocessing model, the CL-SDL application thread and the Listener
thread may not be yielding regularly.  So, in the file
examples/2d-test.lisp of the CL-SDL distribution, I tried adding a
call to MP:PROCESS-YIELD as the last expression in the LAMBDA of
MAKE-UPDATE-FN.

This way both the CL-SDL demo and the Listener can run at the same
time.  CPU usage is over 99% even with just the demo, but OpenGL
applications are quite demanding.

Cool.
