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

+@panic E32USER-CBase 49 if this active object has not been added to the active
