[Click] a question about timer

[Yihong Zhou]

Hi, Eddie:

Thanks for your timely response.  I have a simple question about the timer.  I don't know if my understanding is correct or not.  

Is the timer a kind of task that is looped over by the click thread?  So that when the timer is fired, it is not going to generate a system interrupt.  Instead, it is just like the other tasks such as 'fromDevice', 'ToDevice', etc.
