[boost] shared_ptr<> and atomic_count

Hi-

Looking at the implementation of shared_count<>, it seems as though it
always uses a mutex for incrementing and decrementing the counter.

Is there a reason why we aren't using atomic_count instead?  In the
worst case, it will have the same performance, but in the best case,
it can be significantly faster (BOOST_USE_ASM_ATOMIC_H).

Thanks.
