signal-notify crate provides a simple way to wait for signals in *nix systems through standard std::sync::mpsc API.

```rust use signal_notify::{notify, Signal};

let rx = notify(&[Signal::INT, Signal::HUP]); // block unitl receiving SIGINT or SIGHUP. // recv always return Ok because the sender channel will be never closed. rx.recv().unwrap() ```

signal-notify doesn't support Windows. I'm not familiar with Windows, so I'd be happy if you could help me about it.
