Well, the result is that Emacs doesn't hang. :-) I'm not so worried
about issuing any messages here.
But I wonder -- could we do this (expensive) checking in defface (or
rather custom-declare-face)? That could be helpful -- evalling a
circular face definition should signal an error.
Do we have all the information needed to see whether we have a circular
definition at that point?
