Either way works for me as long as there is something giving me enough
information (or pointer to that) next to the place that allows nullfunc
frames go through. Anyway, Johannes is correct about the proper longer
term fix being better mechanism to stop the queue so that we don't get
into this code in the first place and in that sense, this patch is more
of a workaround for the time being.
