high cpu usage in macOS
Hi, I use the latest version in macOS 10.13, tokio-socks5 cpu usage is very high。
some log:

add some log in: https://github.com/tokio-rs/tokio-socks5/blob/master/src/main.rs#L557
println!("poll.......");and https://github.com/tokio-rs/tokio-core/blob/master/src/net/tcp.rs#L344
if let Async::Ready(x) = r {
println!("poll read {:?}", x)
}log output:
poll.......
poll read Hup
poll.......
poll read Hup
poll.......
poll read Hup
poll.......
poll read Hup
poll.......
poll read Hup
poll.......
poll read Hup
poll.......
poll read Hup
...
...
It looks like HUP, poll read and poll write both Ready but read returns WouldBlock.
let read_ready = self.reader.poll_read().is_ready();
let write_ready = self.writer.poll_write().is_ready();
if !read_ready || !write_ready {
return Ok(Async::NotReady)
}
let n = try_nb!((&*self.reader).read(&mut buffer));some help？
new example for new tokio
this project is still using old api. Is there any plan to rewrite this example using new tokio?

I’m not sure which dependency is trying to link against it though.
Asynchronous DNS support example
Since the first version of tokio-socks5, a couple of futures-based DNS crates appeared, and an example of using one of them for name resolution ought to be helpful as a demonstration of integrating disparate futures-based code bases.
I've adapted the code to use @bluejekyll's TRust-DNS library (with his generous help; thanks!) and would like to open a PR, but since the thread-pool resolver example is valuable, I'd prefer to base the PR on a different branch (the README in master could be updated to announce its existence). Do you agree with that approach, and if so, could you create a new branch?
