I assume they're leaving the door open for implementing that properly at some later date. Incidentally, if the qemu target's sigset_t and the host's sigset_t are different sizes then not just this syscall but I suspect all the others that use sigset_t will have trouble. Luckily only one flavour of MIPS has a non-standard sigset_t size :-) -- PMM
