Here are the cases:

  `C-x C-e' should be the same in every buffer, except that some
  buffers have different Lisp packages associated with them than
  others. In a default OpenMCL configuration it will evaluate each
  `C-x C-e' in a new thread.

  Entering the expression at the REPL is the same except that it
  always uses the same thread, i.e. one thread is dedicated to
  evaluating REPL expressions.

  If you enter it at the *inferior-lisp* prompt then you are bypassing
  SLIME entirely. It will evaluate in the same way as OpenMCL does
  when running without SLIME.

I can't account for this. You're definitely pressing `C-x C-e' and not
return in *inferior-lisp*? Can you give any more details?
