   140 E32USER-CBase 46 panics may occur if an active object is set active but
       
   141 no request is made on its TRequestStatus, or vice-versa. This panic happens
       
   142 no earlier than the next time that the active scheduler assesses which
       
   143 objects are ready to run, and may happen much later. This panic is termed 
       
   144 a 'stray event' because it indicates that some entity has sent an event 
       
   145 to this thread, but this thread is not in a state ready to handle it.
