Now that the response may be fragmented, we may receive early notifications
of aborts in return of poll(), as indicated below, which currently cause
an early error detection :
21:11:21.036600 epoll_wait(3, {{EPOLLIN, {u32=7, u64=7}}}, 8, 993) = 1
21:11:21.054361 gettimeofday({1268770281, 54467}, NULL) = 0
21:11:21.054540 recv(7, "H"..., 8030, 0) = 1
21:11:21.054694 recv(7, 0x967e759, 8029, 0) = -1 EAGAIN (Resource temporarily unavailable)
21:11:21.054843 epoll_wait(3, {{EPOLLIN|EPOLLERR|EPOLLHUP, {u32=7, u64=7}}}, 8, 975) = 1
21:11:21.060274 gettimeofday({1268770281, 60386}, NULL) = 0
21:11:21.060454 close(7) = 0
Just as in stream_sock, we must not believe poll() without attempting to receive,
which fixes the issue :
21:11:59.402207 recv(7, "H"..., 8030, 0) = 1
21:11:59.402362 recv(7, 0x8b5c759, 8029, 0) = -1 EAGAIN (Resource temporarily unavailable)
21:11:59.402511 epoll_wait(3, {{EPOLLIN|EPOLLERR|EPOLLHUP, {u32=7, u64=7}}}, 8, 974) = 1
21:11:59.407242 gettimeofday({1268770319, 407353}, NULL) = 0
21:11:59.407425 recv(7, "TTP/1.0 200 OK\r\n"..., 8029, 0) = 16
21:11:59.407606 recv(7, 0x8b5c769, 8013, 0) = -1 ECONNRESET (Connection reset by peer)
21:11:59.407753 shutdown(7, 2 /* send and receive */) = -1 ENOTCONN (Transport endpoint is not connected)
