+/**

+ * we don't actually filter anything, since sys-even is either on
+ * or off.  The idea is that the actual Listener themselves will perform
+ * a final filter pass, so why do the work twice.  If we were going to 
+ * use proprietary IOCTLs or some other event plumbing that allowed filtering,
+ * we could use the passed in arguments to do useful work.  In short, 
+ * once turned on, we send events of a given type and rely on 
+ * someone downstream to filter.
