Technically its because the SMS interface on Mac laptops is polled,  
rather than interrupt-driven -- the Hid object in the case of the SMS  
won't actually fire any events.  Also, polling it is relatively time- 
consuming.  So rather than ChucK enforcing a specific poll rate, you  
can choose your own according to how expensive it actually is on your  
platform, how much CPU/sample you have to spare, etc.
