> Using a time window of size 6 minutes with a 5 minute advanceBy results in 
> some of the timestamped data being inserted into the previous overlapping 
> window even though the event's timestamp > that window's end time. 
> The fault lies in TimeWindows#windowsFor which does not check that all the 
> windows it's adding have an endTime > event's timestamp.
