简单的tcp echo server
ab -n 1 -c 1 http://127.0.0.1/
总是：apr_pollset_poll: The timeout specified has expired (70007)
抓包又是回了的，请问echo server端缺些什么吗？

strace读完之后，还wait在那，-n 1 -c 1
write(4, "GET / HTTP/1.0\r\nHost: 127.0.0.1\r"..., 77) = 77
epoll_wait(3, {{EPOLLIN, {u32=1433951040, u64=93824994532160}}}, 1, 30000) = 1
read(4, "GET / HTTP/1.0\r\nHost: 127.0.0.1\r"..., 8192) = 77
epoll_wait(3, {}, 1, 30000) = 0
write(2, "apr_pollset_poll: The timeout sp"..., 60apr_pollset_poll: The timeout specified has expired (70007) |
