This is an interesting adapter class that changes a lock into a reverse lock, i.e., on this class calls on the lock, and on this class calls on the lock. One motivation for this class is when we temporarily want to release a lock (which we have already acquired) but then reacquire it soon after. An alternative design would be to add a Anti_Guard or Reverse_Guard class which would on construction and destruction. However, there are *many* varieties of the Guard class and this design choice would lead to at least 6 new classes. One new ACE_Reverse_Lock class seemed more reasonable.
