RequestSubmitDone - Handle submit done callback.
This is our submit done handler, called by the underlying connection
code when a stream is available for our use. We save the stream for
later use and signal the wait event.
We also handle the continuation/termination of a BeginGetRequestStream,
by saving out the result and calling its callback if needed.
Input: SubmitStream - The stream we may write on.
Status - The status of the submission.
Returns: Nothing.
