It could be that re-dumping somehow defeats this mechanism, in which
case we need to debug why it does.  I didn't mean to say that
custom-initialize-delay is a magic wand for this particular case, I
just pointed to a feature that we already have which is supposed to
handle these situations.  If it doesn't work after re-dumping, it
needs to be fixed or generalized to do so, or maybe we should come up
with a similar but different feature.
