FYI, I just committed http://code.google.com/p/unladen-swallow/source/detail?r=1027, which dramatically improves the performance of Unladen Swallow when running with `-j never`, making disabling the JIT at runtime more viable. We're continuing to make progress minimizing the impact of the JIT when running under `-j never`. Progress can be tracked at http://code.google.com/p/unladen-swallow/issues/detail?id=123.
