[Samba] Samba DNS + caching dns on same box

I may be wrong here and am NOT a BIND expert, but my understanding (and 
experience along with documentation) is that BIND, by default, is a 
caching nameserver. When I used BIND at home before Samba 4 was out, it 
cached things perfectly and worked great, even when Roadrunner DNS was 
down. My assumption was that BIND9 working with Samba 4 would be 
similar. DNS requests for domain information (ie: a workstation or 
network device) would be handled by that dynamic S4 zone, cached or not. 
Everything else (such as a lookup for google.com) would be forwarded to 
the external DNS and the result cached on my local BIND server. After 
all, if BIND caches by default, is there a reason this wouldn't work 
just because I added the S4 DLZ?
