Yes. But in most cases only fixed number of threads is needed, so I
think io_service is enough.
And I have another question. Do we need to implement another message
queue or dispatcher if we need another event handler in a special case,
such as gui or thread pool? Or, we have only one public interface (like
io_service) for a "event queue", and repost any native event/message to it?
