-     * We think that the way LoadAuthorization() is working is wrong.
-     * It doesn't reset the list of stored authorizations before reading
-     * the new cookies. Our take is that if a new auth file is to be
-     * read, the only cookies that are to be accepted are those that are
-     * in the new file, not those in the file -plus- those that have
-     * been in the file in the past. Furthermore, if the list can't be
-     * read or it is empty, it should assume that it ignores which co-
-     * okies are valid and thus it should disable any access. Your mile-
-     * age can vary. A less draconian approach could be to leave the old
-     * cookies if the file can't be read and remove them only if the
-     * file is empty.
-     *
-     * Adding the cookies without removing the old values for the same
-     * protocol has an important implication. If an user shares the co-
-     * okie with somebody and later wants to revoke the access to the
-     * display, changing the cookie will not work. This is especially
-     * important with NX. For security reasons, after reconnecting the
-     * session to a different display, it is advisable to generate a
-     * new set of cookies, but doing that it is useless with the current
-     * code, as the old cookies are going to be still accepted. On the
-     * same topic, consider that once an user has got access to the X
-     * server, he/she can freely enable host authentication from any
-     * host, so the safe behaviour should be to reset the host based
-     * authenthication at least at reconnection, and keep as valid only
-     * the cookies that are actually in the file. This behaviour would
-     * surely break many applications, among them a SSH connection run
-     * inside a NX session, as ssh -X reads the cookie for the display
-     * only at session startup and does not read the cookies again
-     * when the auth file is changed.
-     *
-     * Another bug (or feature, depending on how you want to consider
-     * it) is that if the authority file contains entries for different
-     * displays (as it is the norm when the authority file is the default
-     * .Xauthority in the user's home), the server will match -any- of
-     * the cookies, even cookies that are not for its own display. This 
-     * means that you have be careful when passing an authority file to
-     * nxagent or Xnest and maybe keep separate files for letting nxagent
-     * find the cookie to be used to connect to the remote display and
-     * for letting it find what cookies to accept. If the file is the
-     * same, clients will be able to connect to nxagent with both the
-     * cookies.
