+  //     This class serves as a Proxy that ensures our process always
+  //     has the appropriate allocator in place for every operation
+  //     that accesses or updates the Map Manager.
+  //
+  // = DESCRIPTION
+  //     We need this class because otherwise the ALLOCATOR
+  //     pointer will be stored in the Map_Manager that resides within
+  //     shared memory.  Naturally, this will cause horrible problems
+  //     since only the first process to set that pointer will be
+  //     guaranteed the address of the ALLOCATOR is meaningful!

+  // provided by <ACE_Hash_Map_Manager>.  When they are called, they
+  // acquire the lock, set the allocator to the one specific to this
+  // process, and then call down to perform the intended operation.
