[libmicrohttpd] NOTIFY_COMPLETED

[MrDave]

    Hi,
    
    I am using libmicrohttpd in my application and am seeing an
    unexpected sequence of function calls and am wondering if this is
    expected or whether there is something that I've set up
    incorrectly.  
    
    When initiating the daemon, I am setting callbacks for both
    MHD_OPTION_URI_LOG_CALLBACK and MHD_OPTION_NOTIFY_COMPLETED.  Then
    upon answering the request I am doing a
    MHD_create_response_from_callback.  
    
    What I'm observing is that the MHD_OPTION_NOTIFY_COMPLETED function
    is called before the ContentReaderFreeCallback function from the
    response callback.  My expectation was that the callback "cleanup"
    would have been called before the "notify completed".  
    
    The following code snippets may better explain the question.  I am
    seeing that the 'mhd_deinit' function is
    being called before the 'file_free' function. 
    
    
    ----snip-----
      mhd_ops[0].option = MHD_OPTION_URI_LOG_CALLBACK;
        mhd_ops[0].value = (intptr_t)mhd_init;
        mhd_ops[0].ptr_value = NULL;
      
        mhd_ops[1].option = MHD_OPTION_NOTIFY_COMPLETED;
        mhd_ops[1].value = (intptr_t)mhd_deinit;
        mhd_ops[1].ptr_value = NULL;
      
        mhd_ops[2].option = MHD_OPTION_END;
        mhd_ops[2].value = 0;
        mhd_ops[2].ptr_value = NULL;
      
        daemon = MHD_start_daemon (MHD_USE_AUTO |
      MHD_USE_INTERNAL_POLLING_THREAD,
                                   PORT, NULL, NULL,
                                   &answer_to_connection, NULL
                                   , MHD_OPTION_ARRAY, mhd_ops
                                   , MHD_OPTION_END);
    
    ----snip-----
    
      response = MHD_create_response_from_callback (
                  webua->sz, 32 * 1024, &file_reader, webua,
      &file_free);
        ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
        MHD_destroy_response (response);
      
      Thanks.
