question about caching of lame servers

I tried to test the caching of lame servers in bind9 (9.2.4-1sarge1), 
and reviewing the source code, I came to the conclusion that this 
feature is only used as long as there is at least on authoritative name 
server which is not in the lame-cache. As soon as all authoritative name 
servers of a certain domain are in the "lame" state, bind "restarts" the 
lame settings and tries again although all servers are marked as lame.

Is my conclusion correct?

If yes, is there an option to change this behavior (if all servers are 
marked as lame bind should not try at all)?

Further, I not only want to cache lame name servers, but also name 
servers which are down. Is this possible?
