* It is tempting to use object references to identify each RT_Info,
* but that does not work either: first the *contents* of the
* RT_Info must be transmitted between applications, and object
* references are not good identifiers (due to the semantics of
* _is_equivalent())
*
* The handle_t type is used to generate unique identifiers on the
* scheduling service, the Event Service can then refer to any
* RT_Info using either their name or the quicker handle_t.
