Hello everyone, here is a greeting for joining the list.

I want to request console support in asio.

Some reasons:
1. non-block stdin is useful for some applications.
2. Linux can do non-block IO on ttys.

Implementation concept:
1. Linux: if using epoll, first check if target is a regular file. If not,
fall back to threaded non-blocking IO. select(), poll() can be use on any
valid fds.
2. Windows: this garbage doesn't support overlapped console IO. Create a
separate thread for std{in,out,err}, then communicate with the thread.
3. Other *nix: I don't know.

It could already be used through POSIX stream descriptor, but it is too
limited and platform specific. A library can cover these gaps is great.

I hope you like this idea.
