Loading Elisp files should be fairly rare.  But there might be cases
where it can be done repeatedly, but if/when faced with such a situation
we should be able to handle it efficiently e.g. by checking the
load-history (make sure the file did include some definitions before we
bother to scan symbols and rebuild the regexp) since such "run-time
loading" probably won't define new functions.
