   Some of us managed to misinterpret the post as being about as complex as   
   it gets!   
      
   I use circular buffers a great deal in my coding.  For many of my   
   systems, there are UART communication ports (such as for debugging   
   output - when you don't have a screen or standard output, a UART does   
   the job).  There is typically a circular buffer which is piped out to   
   the port via interrupt routines, and when the application code wants to   
   "print" out a message, it gets pushed into the buffer.   
      
   So the kind of thought needed for Ben's "puzzle" turns up in real code,   
   and I've seen people get it wrong.
