[PMC] According to masak++, r38577 causes a SIGBUS on darwin. The code in question has two code paths: one optimized path that recycles RetContinuations, and the normal path which doesn't. The r38577 commit log suggests that the optimized path was enabled in all cases.  But in reality, *both* paths were being executed. This patch disables the non-optimized path.  I can't tell you why this fixes it, but apparently it does.
