    This differs from the standard version in that:
 
-   We do not initialize the "hint" field because it is not the case
-   that the target is in range of something on the stack.  We save
-   a bogus branch-prediction cache line load by not setting "hint".
+   We do not initialize the "hint" field because it only has an 8k
+   range and so the target is in range of something on the stack. 
+   Omitting the hint saves a bogus branch-prediction cache line load.
