+-- the stack limit approach (the limit of the stack is stored into a per
+-- thread variable).
+
+pragma Restrictions (No_Elaboration_Code);
+-- We want to guarantee the absence of elaboration code because the binder
+-- does not handle references to this package.
+
+pragma Polling (Off);
+-- Turn off polling, we do not want polling to take place during stack
+-- checking operations. It causes infinite loops and other problems.
