I'm not sure why to introduce another rate limiting? I mean, corosync 
itself has rate-limit by:
- allow only node which holds the token to send messages
- allow only limited number of messages to be send when holding token 
(you can tweak them by totem.max_messages and totem.window_size)

Itroduce another rate-limit in totemudp(u).c is probably going to create 
less stable membership and various problems... but who knows, you can 
give it a try.
