I'm guessing no to huge benefits though. You may save on startup time but I 
doubt that reading the files in is a large cost. The files are reprocessed into 
a binary in-memory representation at startup, so by runtime there should be no 
performance difference (i.e. we've effectively already discarded comments and 
whitespace). This may not be true for the javascript files though, since I 
javascriptcore may like large JS files to be shrunk and we'd just be passing 
those in to JSC.
