How to catch system signals

[0b01]

Is there something similar to tokio_net::signal::unix::Signal?

Not yet! -- we're aiming for parity with the standard library, so this would be an API we may not want to expose directly from async-std. But I agree we should definitely have a good way of handling signals that's compatible with async-std.

Probably a good way to start would to be to look at signal-hook and see if we can make it compatible with async-std.

Following up on #293. signal-hook crate supports mio by implementing and exposing dyn Evented which in theory could be plugged into a async_std::net::Watcher

I notice @0b01 you says signal-hook implement Evented, so I try to write a crate async_signals to handle signal in async fn. Also I read the async_std::net::Watcher, it seems is not so hard to add signal into async-std
