The GC used to be able to cancel FTL plans if the profiled DFG CodeBlock was going to be jettisoned. Then, we regressed that code and made it so that GC canceled all FTL plans. Then we removed the code to cancel FTL plans, except in cases where the owning executable was dead.
It might be worthwhile to bring some of that code back somehow.
