I'd like a debug function that takes two parameters: * The amount of native stack space to leave available * A callback The function would use alloca to gobble up the difference between a stack dummy and RuntimeFriendFields::get(rt)->nativeStackLimit, then call its callback. This would let my fuzzer create more precise and more portable testcases than my current "nearNativeStackLimit" gadget. I'd also like something similar for script stack space (to replace another gadget, "nearScriptStackLimit"), but I don't understand that as well.
