    Make sanity checking when getting scripts optional
    
    Apparently fixing the bogus-multiple accessible-application instances
    had the unintended side effect of making certain apps less responsive.
    We need to try to figure out the magic combination to prevent double-
    speaking without this side effect. NOTE: This particular change does not
    change the current behavior or fix; it merely makes it possible to turn
    checking off, which will be done on a trial-and-error basis in subsequent
    commits.
