 - The rate limit is a hundred at once, refilled at ten a second (it was 30, one every two seconds, which a page with a picture strip used up in one load: a few reloads and the stylesheet was refused). The files a page is made of, from portal's own disk, are not counted at all. `PORTAL_RATE_PER_SECOND` replaces `PORTAL_RATE_SECONDS`; no site set it.
