Merge 1447 "Fix call to rt_sigaction"

Browse Source 
> Fix call to rt_sigaction
> 
> Despite the fact that many places imply that sigaction and rt_sigaction
> are essentially the same, rt_sigaction's signature is actually
> different-- it takes the size of the kernel's sigset_t as an extra argument.
