+ *
+ *
+ *     This class keeps track of the status of <is_set_>, which can
+ *     be set based on various events (such as receipt of a
+ *     signal).  This class is derived from ACE_Event_Handler so
+ *     that it can be "signaled" by a Reactor when a signal occurs.
+ *     We assume that <TYPE> is a data type that can be assigned the
+ *     value 0 or 1.
