Actually, in this usage (attaching the file descriptor of a listening socket to a main loop) there is no need to make the file descriptor non-blocking since you will not make any blocking calls on it until you actually get to call accept() to establish the connection, and you may get undefined behaviour if you do - I don't know what POSIX says about that when you attempt to use poll() with it. Once poll() indicates that a connection is available, accept() can't block anyway. Does it work if you omit your call to fctl()?
