I've never heard of dnsmasq, but DNSBL queries are regular DNS 
queries, so any normal caching DNS server/proxy should cache 
DNSBL lookups (we use pdnsd).

It is. That's the whole point of using DNS for BLs. You make use 
of an existing, proven and scalable, distributed caching database 
infrastructure.
