That creates an inconsistency.  If it were a reliable solution to the
problem, that could justify the inconsistency.  But it isn't reliable,
because if the file require'd was already loaded in bytecode outside
the compiler, this won't reload it.

Thus, if we want a reliable solution, it has to be something else.

For the same reason, the advice in mh-e.el is not a good solution
(even disregarding that it is a bad thing for parts of Emacs to
advise other parts).
