+ *
+ * They also had an implicit "same size as pointer" characteristic
+ * to them (i.e. Mach's traditional types are very ILP32 or ILP64
+ * centric). We support x86 ABIs that do not follow either of
+ * these models (specifically LP64). Therefore, we had to make a
+ * choice between making these types scale with pointers or stay
+ * tied to integers. Because their use is predominantly tied to
+ * to the size of an integer, we are keeping that association and
+ * breaking free from pointer size guarantees.
+ *
+ * New use of these types is discouraged.
