Why do you think it's wrong? All of the kernel interfaces that take a
sigset_t argument include an additional argument specifying the usable
size of the sigset_t, and the kernel issues an error (EINVAL if I'm
not mistaken) unless the argument matches the kernel's idea of the
size of sigset_t. On MIPS, the expected size is 16.
