We can't report the "server already started" error prior to the call to WebSocketTransformer.upgrade(), because it's possible that a different client will successfully establish a connection during the upgrade process. Instead, check after the call to upgrade(). This means that if there is an error, we have to report it via a RequestError object rather than using an HTTP error. When we add stdio as a transport mechanism, this will have the further advantage of allowing the "server already started" error to be detected by code that is independent of the transport mechanism.
