yes, i know, but this (from README.CONFIG) made me think twice:

i read this as "otherwise processing delay will be variable, depending 
on the jack period size". please correct me if i'm wrong.

the problem is that the initial delay of any reverb effect affects 
mixing decisions a great deal, and i want to make sure it's not a 
function of the jack period size....
