* progresses (executes any scripts, accepts any user keyboard
* input) (already done for you)
* - Check the return code for scheme_interpreter_service. If it
* returns a non-zero value, the application should quit
* - You need to determine whether there are any events pending in
* X lib: call CheckForXEvents().
* - You should call EventQueue's ProcessNextEvent() method to
* process events and service the timers. Note, you should call
* this *even if there are no events pending*, since it will
* service the timers.
* - You can optionally call XFlush() to flush X's queue of
* graphics commands to the X server, but it is likely
* unnecessary given calls to other Xlib functions. See the
* following for more information:
* http://tronche.com/gui/x/xlib/event-handling/XFlush.html
* - You should sleep if there is nothing left to do (i.e., there
* are no events in our event queue or pending in X's event
* queue -- check with XPending). Sleeping for a bit will ensure
* the CPU is not throttled.
* - If you sleep, sleep for a very small amount of time, say
* 1/1000 of a second, to enable interactive typing rates on the
* console. (See the usleep function for fine-grained sleep
* amounts).
* - We *will* check to ensure your app doesn't throttle the CPU
* when idle, so make sure you sleep when there are no events.
