This was noticed while reviewing the code for an unrelated reason, so there is no known problem caused by this. Nevertheless, this is incorrect as the stream is globally visible in the consumer. Moreover, the stream was not cleaned-up which can cause a leak whenever a metadata snapshot fails. Signed-off-by: Jérémie Galarneau Signed-off-by: Jonathan Rajotte ---
