+ * 1). To ensure that when a client creates a "session alarm" (AddWithNotification)
+ *     we are able to correctly DeQueue the right alarm when that session disconnects
+ *	   unexpectedly.
+ *
+ * 2). So that it is possible to identify the owning thread for a given alarm. Each
+ *     CSession2 object has an associated (and underlying RThread). In order to return
+ *     the name of the thread through the client-API we need a method of associating
+ *     sessions with alarms.
