    // variable_set(), which updates the {variable} table and then clears the
    // cache to make sure that the next page request picks up the new value.
    // Not actually clearing the cache here therefore leads old variables to be
    // loaded on the first page requests after installation, which can cause
    // subtle bugs, some of which would not be fixed unless the site
    // administrator cleared the cache manually.
