+Cache cleaning and use for long running emitters
+------------------------------------------------
+
+One of the dangers in using this in long running event emitters is _cache 
+buildup_ -- the data for each event emitted will get stored and this
+might get quite large, this, if not managed, is a potential memory leak.
+
+To deal with this issue a `.clearGuaranteedQueue(<event>)` method is 
+added to the emitter, this will clear the cache for a specific event. 
+This and has a shorthand form `.clearGuaranteedQueue('*')` that will 
+clear the cache for all wrapped events.
+
+So for the above example:
+```javascript
+// This this will drop all the prior match data, so newly registred handlers
+// will not see them...
+// NOTE: this will not affect the underlaying glob object in any way. 
+results.clearGuaranteedQueue('match')
+
+```
