In the case where an operation can't be done in-place, Pd's insistence on 
reusing the same buffer will cause a slowdown because not only the data 
has to be copied out of the buffer, but it has to be copied back in, 
because Pd doesn't provide that option that Max provides. Hence Max is 
faster (for this aspect).
