i find this wholly inadequate as a description.
specifically, it's missing a motivation.

and how would one use this in a meaningful way, given that the actual 
silence size is dependent on the period size and preferably the pointer 
alignment?

what i could imagine _hypothetically_ making sense is making the 1/10th 
sec "overshoot" configurable, as it's hardware-dependent. but in 
practice, i don't see how that would be actually useful, as the cost of 
doing too much is negligible, and the default you chose seems more than 
safe enough.
