Ah yeah. Good point, because it may handle an exception on the same stack. I had originally believed that this Post-RA Machine scheduler was running after this, and it could do the same kind of re-arranging. Looking again it seems that it's treating the stack pointer as a scheduling barrier.

The SP was not my motivating case. I'll can easily remove it from this patch.
