For info, I put a little study I did about the byte code compiler and other speedup approaches (but not multicore) on the Rwiki at

http://rwiki.sciviews.org/doku.php?id=tips:rqcasestudy

which looks at a specific problem, so may not be relevant to everyone. However, one of my reasons for doing it was to document the "how to" a little.
