That part was actually confusticate's and I do believe that he was implying that the sounds had load() called prior to the KeyboardEvent, and the latency happens on the 100th keystroke as well as the first.
By way of comparison, I had the same problem in sounds attached from the library. I wonder if it would make a difference if new Sound objects (in AS2) or SoundChannels (in AS3) were or weren't instantiated every time.
