I thought I merged this years ago; today we have spent two hours
figuring out why the server running mpd(8)'s PPTP with manually
added host routes was not (randomly) forwarding IP datagrams to
the remote end of the PPTP connection.  It was a BIG surprise
when I figured out I did not MFC this fix.

BTW, Archie, kudos for making mpd(8) work in a scenario documented
in the BUGS section of libalias(3).  How this is done?
