hello!

yesterday i got curious about how fibers work, and if the can be 
used as a replacement in network programming. so i started 
hacking a small example together, which is hopefully useful to 
other D beginners too :)

Two things:

In the line `string s = (cast(immutable(char)*)buf)[0..len];`, 
the cast to immutable is unsafe, as `buf` is modified on the next 
iteration and so the slice into it is not actually immutable. 
`writeln` can take a regular `char[]` fine, so you can just drop 
the immutable; otherwise you can do 
`cast(string)((buf[0..len]).idup)`.

Also, using select/poll/epoll would be better than looping and 
sleeping. std.socket includes a SocketSet class for doing this 
(though the API for it is kinda bad).
