Quick question: how is Activity Monitor being used to make this
conclusion? If you are looking purely at total memory usage, one
thing to consider is that SndBuf allocates memory to store the entire
file in memory as soon as it is opened, regardless of your chunk
size. Not that, like, ChucK has never had a bug or anything... just
want to make sure we're not chasing shadows.
