Martin, is there any practical way of preserving a
window-configuration across Emacs sessions?  The object
current-window-configuration returns is exposed to Lisp as an opaque
object, and I don't think we can meaningfully serialize it, can we?

So perhaps the solution is to filter such registers from
register-alist when we save desktop?

No, that's a very different issue, and it has been solved long ago,
AFAIR.
