Yet another reason ppp has no business doing routing.  This leaves
a window of time that no default route exists and if a connection
happens to send a keepalive packet during it the conneciton is going
to get torn down :-(.

Correct thing to do is a ``if route 0 exists, then route change 0 0,
else route add 0 0''.
