-// Mock implementation of Pipeline.  Simply provides getters/setters for every
-// pipeline state variable and queues all tasks posted to the "pipeline thread."
-// Since there actually isn't a separate thread unit tests can control when
-// they want to execute queued tasks by calling RunAllTasks(), which helps to
-// assert pre- and post-conditions.
