Wonderful! I was just thinking about replacing CBDATA, yesterday or so.

Could we not simply make Squid depend on Boost? Or copy the Boost smart
pointer library implementation into the Squid source? Boost's license is
very relaxed:

This would remove RefCount<> first, then hopefully CBDATA in the future.
 The nice thing about using Boost is that if the library is added to C++
in the (admittedly distant) future, our API would not need to change,
and our copy of the Boost implementation could be kept around for older
compilers.
