Nonblocking IO for stdin

[gareis]

So I modified Phobos somewhat so I could make a socket to associate with 
stdin and thereby see if there was any input ready. There were two 
problems with this: first, there was a false positive upon starting the 
program, so it hanged for input; second, it did not acknowledge any 
further keyboard input.

The only solution I see currently is to use threads. That should be 
relatively safe, given that the input thread should never need to 
interact with the output thread. I hope.
