Should:

    (fmakunbound '(setf foo))

remove the setf method for foo in the case where that method was defined
with DEFSETF or DEFINE-SETF-METHOD, or only when the setf method was
defined with:

    (defun (setf foo) ...)
or
    (setf (fdefinition '(setf foo) ..)

Thanks for any thoughts on this.

John.
