 * timer_test is supposed to demonstrate that window system
 * event related callbacks (like the keyboard callback) do not
 * "starve out" the dispatching of timer callbacks.  Run this
 * program and hold down the space bar.  The correct behavior
 * (assuming the system does autorepeat) is interleaved "key is 
 * 32" and "timer called" messages.  If you don't see "timer
 * called" messages, that's a problem.  This problem exists in
 * GLUT implementations through GLUT 3.2.
