Sure.
What a discussion... Well I'm happy for the past lazy days. 


I've include some references in the experiment from last week and it should 
be interesting for people in this discussion.

Summary:
Forwarding experiment with different rates of new incoming destinations/sec. 
Ranging from DoS attack to single destination flow. With full 123k routes.

Your latest patch looks interesting... good thinking. Operations and tuning 
would be simplier. Hope to have time for a test tomorrow. Testing is very 
manual work still.

Cheers.
