patch for linux version

[GoogleCodeExporter]

打了这个补丁后，在 linux + py2.6 
中虽然还出现如下错误，但似乎不影响运行。

----------------------------------------
Exception happened during processing of request from ('127.0.0.1', 45781)
Traceback (most recent call last):
  File "/usr/lib/python2.6/SocketServer.py", line 558, in
process_request_thread
    self.finish_request(request, client_address)
  File "/usr/lib/python2.6/SocketServer.py", line 320, in finish_request
    self.RequestHandlerClass(request, client_address, self)

  File "dns.py", line 20, in handle
    rspdata = self._getResponse(data)
  File "dns.py", line 41, in _getResponse
    rspdata = sock.recv(65535)
error: [Errno 11] Resource temporarily unavailable
----------------------------------------

不知道 win 版是否也有此问题？

另外能否简要说明一下原理，或者给个参考资料看看。

还有 sock.recv(65535) 
这里面，65535是不是太大了，我简单测试了一下 rspdata
的长度，似乎没有超过 500的。

谢谢，已将patch合并到项目中。rspdata的长度只要大于可能出��
�的包长度都是正确的
