Did we forget to call `set_nonblocking` in `examples/from_std_listener.rs`?

[nojima]

The documentation for TcpListener::from_std says:

The caller is responsible for ensuring that the listener is in non-blocking mode. Otherwise all I/O operations on the listener will block the thread, which will cause unexpected behavior.

However, examples/from_std_listener.rs doesn’t call set_nonblocking. Is it intentional / safe to omit it here?

Having just run into this problem after copying the examples - my guess is yes 😄
