I put just that little bit of code into tiny-servlet.ss, typed  
mzscheme tiny-servlet.ss at the [OS X] command line, and my browser  
popped up with the working servlet.  Wow was that easy!

$ mzscheme tiny-servlet.ss
Your Web application is running at http://localhost:8000/servlets/standalone.ss 
.
Click 'Stop' at any time to terminate the Web Server.
   C-c C-c
Web Server stopped.
