When changing an indirect route, kernel routing code allocates
a route to the gateway and caches it in the route structure.
It may happen (if the routing table is screwed) that the gateway
route is the same route as the one being modified, in which case
a kernel reports EDQUOT. Be more verbose about this:
# route add -net 10 192.168.4.65
add net 10: gateway 192.168.4.65
# netstat -rn -finet

Before:
# route change -net 10 10.0.0.1
route: writing to routing socket: Disc quota exceeded
change net 10: gateway 10.0.0.1: Disc quota exceeded
After:
# ./route change -net 10 10.0.0.1
route: writing to routing socket: Disc quota exceeded
change net 10: gateway 10.0.0.1: gateway uses the same route
