That's not a problem (as in "bug", which were fixed by Ken, at least
those that we know about).  This "problem" is a limitation of the
method, and I'm not sure the method implemented on the branch can be
significantly sped up, unless we completely rethink what Lisp we load
at startup and how.

This limitation is exactly the reason why we will soon have to decide
whether we merge the branch and start using it, improving what can be
improved and living with that which cannot, or keep using unexec at
least till Emacs 27.
