I can confirm the behavior you describe, though I can't tell why this is
so, or what's wrong. It looks like the socket returned by the (async)
accept() call somehow inherits the non-blocking flag from the listening
socket, but fcntl() doesn't see it. I might miss something, but it looks
strange to me as well. I'll try to find out more about it.
