I feel there should be no need to change anything on the c side for
"syntactic sugar"
this is what I commited to CVS:

+    alias save_internal save
+    def save
+        if block_given?
+            save_internal
+            begin
+                yield
+            ensure
+                restore
+            end
+        else
+            save_internal
+        end
+    end

If this were to change in the .c file, I'd prefer doing the yield
there as well. It's a matter of taste though.
