| I even put the line (1) into my ~/  *print-circle* remains NIL
| :-(

  I had to investigate this because it appears to be the only variable that
  this happens to.  Now, there are some curious bindings in the Lisp Emacs
  Protocol implementation.  editor-connection-server binds *print-circle*
  to nil, and the function that actually evaluates the form that the editor
  server has received also specifically binds *print-circle* to nil.  This
  is very strange.  There are no comments explaining this in the code,
  there is nothing in the documentation that I can find to explain this,
  but *print-circle* clearly is treated very specially.  This curiosity
  means that evaluating any form that produces a circular form of any kind
  will cause that Lisp evaluation process to produce infinite amounts of
  output.  Now, Franz Inc has specifically ensured that *print-circle* is
  nil, so this is no ordinary bug, but a design choice.  This is very odd.

  In a fight for something, the fight is a loss, victory merely relief.
