...uh, strictly speaking you're right, but I do remember a 'single 
buffer' mode working in earlier versions of the GEM OSX port...I think 
it was one of ben's early example patches:  but as I recall, ya had to 
select single buffer before creating the window, which resulted in the 
buffer getting filled by all drawing events, which was cool as long as 
ya had a way to change your drawing colors/shapes/etc...I haven't tried 
this in awhile, so I'll look into it tonight...
