+//  typedef <implementation-defined> ndnboost::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...
