does there need some update with guide and tests?

I try to compile the basic_stream.cu, but it seems need to explicitly specify the dev_id to Stream constructor. When i try to pass the parameter to constructor and build successfully, it is aborted with message:
"Default GPU stream was used when MSHADOW_FORCE_STREAM was on".
and the test code which doesn't specify the stream explicitly will also give the message above.
I tried to make it works, but i currently doesn't know the rationale behind the stream.
