I think you want to get rid of the above line.

MrEd will continue to run as long as a window is open, or as long as
code in the main thread is still executing. In the your example `(yield
(make-semaphore 0))' never returns --- that is, it never stops
executing --- in the main thread, so MrEd can't exit.
