-        <p>The February 2002 change to the Boost smart pointers introduced a number of 
-            changes. Since the previous version of the smart pointers was in use for a long 
-            time, it's useful to have a detailed list of what changed from a library user's 
-            point of view.</p>
-        <p>Note that for compilers that don't support member templates well enough, a 
-            separate implementation is used that lacks many of the new features and is more 
-            like the old version.</p>
-        <h2>Features Requiring Code Changes to Take Advantage</h2>
-        <ul>
-            <li>
-                The smart pointer class templates now each have their own header file. For 
-                compatibility, the <a href="../../boost/smart_ptr.hpp">&lt;boost/smart_ptr.hpp&gt;</a>
-            header now includes the headers for the four classic smart pointer class 
-            templates.
-            <li>
-                The <b>weak_ptr</b>
-            template was added.
-            <li>
-                The new <b>shared_ptr</b> and <b>shared_array</b> relax the requirement that 
-                the pointed-to object's destructor must be visible when instantiating the <b>shared_ptr</b>
-            destructor. This makes it easier to have shared_ptr members in classes without 
-            explicit destructors.
-            <li>
-                A custom deallocator can be passed in when creating a <b>shared_ptr</b> or <b>shared_array</b>.
-            <li>
-                <b>shared_static_cast</b> and <b>shared_dynamic_cast</b> function templates are 
-                provided which work for <b>shared_ptr</b> and <b>weak_ptr</b> as <b>static_cast</b>
-                and <b>dynamic_cast</b>
-            do for pointers.
-            <li>
-                The self-assignment misfeature has been removed from <b>shared_ptr::reset</b>, 
-                although it is still present in <b>scoped_ptr</b>, and in <b>std::auto_ptr</b>. 
-                Calling <b>reset</b> with a pointer to the object that's already owned by the <b>shared_ptr</b>
-            results in undefined behavior (an assertion, or eventually a double-delete if 
-            assertions are off).
-            <li>
-                The <b>BOOST_SMART_PTR_CONVERSION</b>
-            feature has been removed.
-            <li>
-                <b>shared_ptr&lt;void&gt;</b> is now allowed.</li>
-        </ul>
-        <h2>Features That Improve Robustness</h2>
-        <ul>
-            <li>
-                The manipulation of use counts is now <a name="threadsafe">thread safe</a> on 
-                Windows, Linux, and platforms that support pthreads. See the <a href="../../boost/detail/atomic_count.hpp">
-                    &lt;boost/detail/atomic_count.hpp&gt;</a>
-            file for details
-            <li>
-                The new shared_ptr will always delete the object using the pointer it was 
-                originally constructed with. This prevents subtle problems that could happen if 
-                the last <b>shared_ptr</b> was a pointer to a sub-object of a class that did 
-                not have a virtual destructor.</li>
-        </ul>
-        <h2>Implementation Details</h2>
-        <ul>
-            <li>
-                Some bugs in the assignment operator implementations and in <b>reset</b>
-            have been fixed by using the "copy and swap" idiom.
-            <li>
-                Assertions have been added to check preconditions of various functions; 
-                however, since these use the new <a href="../../boost/assert.hpp">&lt;boost/assert.hpp&gt;</a>
-            header, the assertions are disabled by default.
-            <li>
-                The partial specialization of <b>std::less</b> has been replaced by <b>operator&lt;</b>
-            overloads which accomplish the same thing without relying on undefined 
-            behavior.
-            <li>
-                The incorrect overload of <b>std::swap</b> has been replaced by <b>boost::swap</b>, 
-                which has many of the same advantages for generic programming but does not 
-                violate the C++ standard.</li>

+//
+//    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: nothing
+//
+//  --a;
+//
+//    Effects: Atomically decrements the value of a
+//    Returns: (long) zero if the new value of a is zero,
+//      unspecified non-zero value otherwise (usually the new value)
+//
+//    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...
+//
