[Vortex] More strange behavior during MSG/ANS pattern

[Yourch, Chris]

I have noticed that when I step through my code with my debugger on the
client side that it seems to slow operations down enough for the replies
(via vortex_channel_send_ans_rpy calls on the server side) to get back
to the client. What my code is doing is sending a file from server to
client. The error message I am usually getting is "client have
disconnected without closing session". Here's the simplified code.

CLIENT:

Channel = get_channel_from_my_channel_pool();
vortex_channel_send_msg(channel, output_buffer_ptr,
output_buffer_length, &msg_no);

// Execution goes back to GUI at this point.

// This is the simple frame handler on the client.
void client_frame_handler()
{
     // Get the payload here and write to a file on the local machine.
}



SERVER:

void Frame_handler()
{
  int msgno = vortex_frame_get_msgno(frame);
  Loop and read a file here
  {
      ReadFileChunkHere();
      vortex_channel_send_ans_rpy(channel, file_chunk, file_chunk
_length, msgno);
  }

  vortex_channel_finalize_ans_rpy(channel, msgno);
}
