mutual forwarders in ISC BIND

This question is not directly related to FreeBSD, but perhaps some
network administrators reading this list know the answer.

Can I setup several ISC BIND servers to be each other's mutual forwarders?
Will it work or create an endless loop of DNS queries?

I have customers using several DNS servers as recursive resolvers. The
usage pattern is pretty much equal between all the servers. What I
want is create a cache common to all the recursive servers to reduce
traffic and response time (much like squid siblings work). 

Thank you for any input.
