-//  typedef <implementation-defined> cutl_details_boost::detail::atomic_count;
-//
-//  atomic_count a(n);
-//
-//    (n is convertible to long)
-//
-//    Effects: Constructs an atomic_count with an initial value of n
-//
-//  a;
-//
-//    Returns: (long) the current value of a
-//
-//  ++a;
-//
-//    Effects: Atomically increments the value of a
-//    Returns: (long) the new value of a
-//
-//  --a;
-//
-//    Effects: Atomically decrements the value of a
-//    Returns: (long) the new value of a
-//
-//    Important note: when --a returns zero, it must act as a
-//      read memory barrier (RMB); i.e. the calling thread must
-//      have a synchronized view of the memory
-//
-//    On Intel IA-32 (x86) memory is always synchronized, so this
-//      is not a problem.
-//
-//    On many architectures the atomic instructions already act as
-//      a memory barrier.
-//
-//    This property is necessary for proper reference counting, since
-//      a thread can update the contents of a shared object, then
-//      release its reference, and another thread may immediately
-//      release the last reference causing object destruction.
-//
-//    The destructor needs to have a synchronized view of the
-//      object to perform proper cleanup.
-//
-//    Original example by Alexander Terekhov:
-//
-//    Given:
-//
-//    - a mutable shared object OBJ;
-//    - two threads THREAD1 and THREAD2 each holding 
-//      a private smart_ptr object pointing to that OBJ.
-//
-//    t1: THREAD1 updates OBJ (thread-safe via some synchronization)
-//      and a few cycles later (after "unlock") destroys smart_ptr;
-//
-//    t2: THREAD2 destroys smart_ptr WITHOUT doing any synchronization 
-//      with respect to shared mutable object OBJ; OBJ destructors
-//      are called driven by smart_ptr interface...
