Sorry, I don't understand (probably because I missed the beginning of
this discussion): what do you mean by "background fontification", and
what does it mean for that to have been "completed"?  I'm afraid we
are not on the same page wrt JIT font-lock related terminology.

Parsing by whom? by CC Mode?  If so, CC Mode parsing is itself part of
fontification, AFAIU, and is invoked by the JIT font-lock machinery.
So I'm confused wrt what you are looking for.
