> When changing the uuid configuration (by PUT to _config/uuids/algorithm), a client attempting an operation at the same time experiences a transitory connection refused problem.
> Attached is a patch that changes couch_uuid.erl so that it changes its internal state when the configuration changes rather than the current behavior of stopping and then being restarted by the supervisor.
