As nice as this sounds in theory, lets wait untill people can get 

their hands dirty with it. Most things like this have a huge caveat 

Who knows, maybe it will be 2x faster, but somehow I doubt that.

their hands dirty with it. Most things like this have a huge caveat  
which no one mentions from the get go.

The LLVM optimization is most likely what leads to such improved  
performance. Jitter shouldn't see any improvements from MT OpenGL,  
since all OpenGL commands in Jitter are made from one thread. LLVM is  
Leopard only.
