在客户端断开socket连接后mysock.accept()会不停的返回0，没有断开连接的情况下是阻塞的...............
至于非阻塞
socket.setblocking(flag)
Set blocking or non-blocking mode of the socket: if flag is 0, the socket is set to non-blocking, else to blocking mode. Initially all sockets are in blocking mode. In non-blocking mode, if a recv() call doesn’t find any data, or if a send() call can’t immediately dispose of the data, a error exception is raised; in blocking mode, the calls block until they can proceed. s.setblocking(0) is equivalent to s.settimeout(0); s.setblocking(1) is equivalent to s.settimeout(None).
设置socket.setblocking(0)
但python默认是阻塞的
