I absolutely agree. Interprocess will suffer big portability problems 
with this approach, but the only atomic functions I've seen officially 
in Boost are those implemented in shared_ptr. Ideally, we should have 
some basic atomic library/internal header (even if all atomic functions 
issues a full barrier on each operation) ASAP.

I really don't want to maintain something that I don't understand ;-)
