Re: slow redisplay after changing cursor color

    An much simpler approach would be to state in the docs (manual and doc
    string) that the effect of deriving other faces from "cursor",
    "mouse" and a few other special-purpose faces is undefined.

    We could even give those faces a special 'no-derive property so
    e.g. defface / customize-face could check for and avoid such faces.

    Then we can handle those faces specially  by simply not calling
    free_all_realized_faces when changing them.

That sounds good.  Please do it?
