The only thing that would work is
void __rethrow_cancellation() { }
and then do something like
if (get_cancelation_handler() == __rethrow_cancellation)
_Unwind_Resume (current_exception);
in __cxa_end_catch. Which seems kinda gross to me.
Keep in mind that __cancel_cancellation WILL NOT WORK without help from
and buy-in from the pthread library. Which does not currently exist.
