Atomically Thread-Safe Reference Counting...

Currently, Boost doesn't provide support for atomic reference counting;
shared_ptr falls under 'basic' thread-safety. I propose a reference
counting algorithm that falls under 'strong' thread-safety. Here is a
experimental prototype I created:

A SPARC 32-64 version is underway. Here is some more information on my
algorithm:

(initial idea; pseudo-code)

(mostly lock-free...)

(possible improvements...)


Does anybody think that Boost could possible benefit from this level of
thread-safety? Any thoughts?


Thank you all for you time!
