Oh you got me wrong here, I wanted to use the deadline timers and probably
several network connections with low traffic.

So I thought if there was a completion criteria that says, "anything
to read", I
could do pretty much everything I need with the existing asio. Well, at least
on Unix-like systems (x11,file alteration, directfb; linux joysticks can be
easily parsed into a event data structure). Windows seems like a completely
different story.
