POSIX signal values (union sigval) is an application defined extra parameter of signals. It could be
delivered by sigqueue, or timer_create etc. In some situations this is very useful. But now we can't get it in Go. I've tried to implement this as an external package but it seems impossible.

This really doesn't fit into os/signal. It doesn't seem impossible, though: if you really need to handle that information you can use cgo to register a signal handler in C and handle those from the C side.

Thanks for the suggestion. I'll use cgo to do that.
