> It looks like we should set isTimerActive to true when flushTimerTask is scheduled. Otherwise if a new qualified event comes before the current flush timer is expired,  flushTimerTask will be canceled and rescheduled.
> Also I didn't find any code which set isTimerActive flag to true, So isTimerActive is useless in current code.
