+Summary: [2.0] System.Collections.Generic.List lazy init is broken
+
+The following test case:
+
+System.Collections.Generic.List<string> test = new System.Collections.Generic.List<string>();
+test.Insert(0, "a");
+test.Insert(0, "b");
+
+throws an exception due to initing with 0 size (it tries to shift and insert into a null array)
+
+adding:
+data = new T [DefaultCapacity];
+in the empty .ctor will fix this; however we will loose the gains of lazy initing.  Is the check in each 
+method versus lazy init benefit worth the cost?
