-   --  Ada priorities are used as follows:
-
-   --  256        is reserved for the VxWorks kernel
-   --  248 - 255  correspond to hardware interrupt levels 0 .. 7
-   --  247        is a catchall default "interrupt" priority for signals,
-   --             allowing higher priority than normal tasks, but lower than
-   --             hardware priority levels.  Protected Object ceilings can
-   --             override these values.
-   --  246        is used by the Interrupt_Manager task
