I thought the network socket was the bottleneck.  The example I am  
thinking of is getting the mouse pointer coords from Tk.  That  
generates a lot of network traffic, it would be nice this happened in  
the pd process instead.  Obviously, using the C interface to draw to  
the screen wouldn't be useful.
