Indeed the entry for make-variable-frame-local is hard for me to
parse.  I sometimes think that this function turns a variable into a
frame parameter.

    This does not create any frame-local bindings for VARIABLE,
    it just makes them possible.

    A frame-local binding is actually a frame parameter value.
    If a frame F has a value for the frame parameter named VARIABLE,
    that also acts as a frame-local binding for VARIABLE in F--
    provided this function has been called to enable VARIABLE
    to have frame-local bindings at all.

    The only way to create a frame-local binding for VARIABLE in a frame
    is to set the VARIABLE frame parameter of that frame.  See
    `modify-frame-parameters' for how to set frame parameters.

But as you say, none of this seems to work.
