Transparently parameterizes synchronization into basic arithmetic operations.
This class is described in an article in the July/August 1994 issue of the C++ Report magazine. It implements a templatized version of the Decorator pattern from the GoF book.
Certain platforms may provide a template specialization for ACE_Atomic_Op <ACE_Thread_Mutex, long> that provides optimized atomic integer operations without actually requiring a mutex.
