Hi,

you can easily do this using Boost.Atomic and intrusive_ptr:
http://www.chaoticmind.net/~hcb/projects/boost.atomic/doc/atomic/usage_examples.html#boost_atomic.usage_examples.example_reference_counters 
<http://www.chaoticmind.net/%7Ehcb/projects/boost.atomic/doc/atomic/usage_examples.html#boost_atomic.usage_examples.example_reference_counters>

It should be easy to make (un-)reference and counter-operations atomic 
using this ;)
