+Summary: Unnecessary allocations in System.Runtime.Serialization
+
+System.Runtime.Serialization.ObjectIDGenerator needs to maintain a
+Hashtable in which the keys are object instances.  To do this, it
+introduces an InstanceWrapper class which overrides Equals and GetHashCode,
+and uses those objects as the Hashtable keys.  However, this means that we
+have to allocate one of these objects for every Hashtable lookup.
+
+It would be much more efficient (and not any more difficult) to instead
+create a custom IComparer, passed in as an argument to the Hashtable's
+constructor.
