Well I didn't notice any info on which VM it is. However if you draw  
*each* pixel via Morphic/BitBlt confusion then mmm it will be slow
The unix vm does a draw a pixel, flush, that will take forever,  
earlier versions of the mac carbon vm also did the same. Current  
draw a pixel but regulate flushing, so it's *slow* but not render  
each pixel slow...
