What is the behaviour of boost::detail::atomic_count overflow?  I
realize that overflow for a signed long is undefined, but it is
possible that each platform-specific atomic increment operator handles
overflow in some documented way, which in sum would constitute a
defined behaviour for atomic_count overflow.  Documenting this
behaviour (along with that of underflow, which is presumably the same)
in the atomic_count documentation would be extremely helpful.
