// Used to signify that streams are multiplexed and therefore need a StdWriter to encode stdout/stderr messages accordingly.
// TODO @cpuguy83: This shouldn't be needed. It was only added so that http and websocket endpoints can use the same function, and the websocket function was not using a stdwriter prior to this change...
// HOWEVER, the websocket endpoint is using a single stream and SHOULD be encoded with stdout/stderr as is done for HTTP since it is still just a single stream.
// Since such a change is an API change unrelated to the current changeset we'll keep it as is here and change separately.
