JSC limits recompilation only in the sense that we have exponential back off on each jettison. But that means that a sufficiently hot function will keep getting recompiled forever even if speculation is permabroken in that function. Other than that JSC has only very weak heuristics for aging out code. And on sufficiently empowered devices our JIT pool is hundreds of megs. So, we will happily compile your whole program with the jit if your whole program is warm and runs long enough.
