+**      "ready" states.
+**
+**      The CFE "main" thread starts individual tasks for each of the core applications
+**      (except FS).  Each of these must perform some initialization work before the
+**      next core application can be started, so the main thread waits to ensure that the
+**      application has reached the "ready" state before starting the next application.
+**
+**      If any core application fails to start, then it indicates a major problem with
+**      the system and startup is aborted.
+**
+**      Units are in milliseconds
+**
+**  \par Limits:
+**       Must be defined as an integer value that is greater than
