+    !! Prototype: int SafeFetch32 (int * adr, int ErrValue)
+    !! The "ld" at Fetch32 is potentially faulting instruction.
+    !! If the instruction traps the trap handler will arrange
+    !! for control to resume at Fetch32Resume.  
+    !! By convention with the trap handler we ensure there is a non-CTI
+    !! instruction in the trap shadow.  
+    !!
+    !! The reader might be tempted to move this service to .il.
+    !! Don't.  Sun's CC back-end reads and optimize code emitted 
+    !! by the .il "call", in some cases optimizing the code, completely eliding it,
+    !! or by moving the code from the "call site".
