Cache cleaning and use for long running emitters
------------------------------------------------
This is not recommended for use in long running event emitters as each
event emitted data will get stored and might get quite large, i.e. a
potential source for a leak.
To deal with this issue a `.clearGuaranteedQueue(<event>)` method is
added to the emitter, this will clear the cache for a specific event and
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 matches, so newly registred handlers
// will not see them...
results.clearGuaranteedQueue('match')
```
