Comment:

 Your stream implementation does not strictly adhere to the
 [http://www.boost.org/doc/libs/1_49_0/doc/html/boost_asio/reference/AsyncReadStream.html

 AsyncReadStream requirements]:

   If the total size of all buffers in the sequence mb is 0,
   the asynchronous read operation shall complete immediately
   and pass 0 as the argument to the handler that specifies
   the number of bytes read.

 The async_read_until implementation relies on this behaviour to deliver
 the completion handler when the streambuf already contains the delimiter.
