(From update of attachment 111720)
lastSeenCallee isn't marked so this isn't safe, but also this may result in dead functions being kept alive longer than is strictly necessary.  I would almost consider going with a Weak<> ref rather than WriteBarrier<JSFunction> if we can get do it without a perf impact
