[99s-extend] timeout in cowboy loop handler

[Loïc Hoguin]

Infinite is bad practice, yes. Infinite means some connections will 
*never* be closed, eating FDs and memory for nothing.

I'm not sure why you want to receive messages, you could just use a 
normal handler that asks for more data, sends it, ask for more data, 
sends it, etc.
